I was trying my best to NOT buy heads this year (financial reasons) but it seems I am just going to have to pony up and get a set. (who needs food, right?? :) :) :) LOL)
So here is what I have as far as engine goes:
1915
SCAT 20006, c45 grind cam
Duel 40's :Main-115, Air-220, Idle-57
Not sure what else to tell ya. I do want good heads but I have to keep in mind the cost. I also want to race it (dirt drags, A.C.) but it is just for fun. I'm not so competitive that I need to win. Just have a fun fast time.
Please give me your thoughts.

Something like CB Performance Panchitos 044 head would work.
There a thread on them in the performance section.

Thanks Joseph. I appreciate it!!
I will look into these but, to be perfectly honest, I'm not sure I know what I'm looking at. I read the thread but most of it goes over my head. I'd like to call CB and get their opinion but, I'm not a fan of "asking the source". I really would like you guys input. I just don't want to make a regrettable mistake. I already regret what I had built.
Also, are these just "bolt-on and play"?? is there anything else i need?
Thanks again!!

The thread on the Panchito head was started by Pat Downs. He works for CB Performance and does a lot of research and development for them.
If you go to their website there is pictures and information about the heads and the flow numbers are there too. Also the chamber volume is listed.
Like any other cylinder head installation, it just not bolt them on and go. You are going to need to find out what compression ratio you want to have. That requires checking what the deck height of the engine you are installing the heads on. And even though the chambers are listed as being CC for volume it is wise to check or make sure that what CB says is true.
You may also need a different set of push rods as you may need longer or shorter.
When building a high performance engine it not like just putting together a stock engine.

There is also http://mofoco.com/ in Wisconsin that makes cylinder heads. Talk to Roy, he may have information that can help you make a decision on what you need.

The CB 044 Panchito heads would be great for your 1915. You will also need to have your manifolds match ported. Remove your old heads and measure the deck height so you can order new heads with the combustion chamber CC's you need to get the compression ratio you want. After you install the new heads you may have to have your push rods cut to get the rocker arm geometry correct.

You really need to look around in the Performance engine forum for specific engine questions/information. There are a lot of engine guys that don't have a Buggy and don't look in this forum.

I just talked to Marie Ann @ CB. she said to make sure the deck height is sixty thousandths and to get the heavy duty aluminum push rods along with the 1673 heads (94 bore).
What does that sound like to you guys??
She also said I may need shims to achieve the deck height. I understand there are under jug and under head shims. Which ones would be best?
Sorry for all the questions, I just want to get this right.
Thanks again guys!

I would try to avoid head spacers top side, do you know the Deck Height of the piston in the cylinder yet? DRD L5's.

Nope, not yet. I guess I need to pull it apart so I can order it all at the same time. I'm going to HATE not having it to drive. I'm in it every chance I get.

That's awesome!!! Coolest thing I've seen on the Samba all month!!!

I want a pair!!!!

Doesn't do you a lot of good as you don't yet know your deck ht. . CB has a 10% off sale this weekend. A set of the new Panchito heads with dual springs, cc to your specs and shipped to Indiana is right around $700. Add ti retainers for $45 more if wanted.

That is a pretty darned good deal for these heads I think.

Fri Jul 01, 2016 7:14 pm

I just use barrel shims at the case. Don't like the copper head gaskets.

Looks like with a Scat C45 Camshaft it's going to be a high compression engine (9:1) or something, so it's not going to need head gaskets! Probably won't get even have the .060" Deck to the head either at least not 68cc combustion chamber heads. Probably looking at 53cc heads and .030" Deck. Looks like the Panchito 044 would be much prefered in this case!

Quick question:
I was talking with a friend and he was wondering why they don't use 42 or 44 intake valves? Is it because they are able to get good flow with the design of the heads??
This inside a VW motor is a bit new to me.
He was also saying that .030 deck height is doubtful. Probably .060 and over. And at that point, I would not have enough compression. He felt that 9:1 should be minimum.
Thoughts??

Sat Jul 02, 2016 10:15 am

I have never used big valves myself because I am always building engines for torque and lower RPM not Power and High RPM. A lot of folks for sure are doing the large valve heads though. Price is a big consideration, not just the cost of the heads but the rest of the engine to handle RPM's over 6000 RPM.
DRD L3 heads would be for stock valves 35.5mm X 32mm (What I have been using.)
DRD L5 heads have 40mm X 35.5mm valves as do the CB Panchito 044 heads,
DRD L7 heads have 44mm X 37.5mm valves and there are Street Eliminators that come in various valve sizes.

I was reading on these link's that I have posted above and the CB-Performance ad says right in the ad for the Panchito 044's that they can machine them for higher compression engines.

"The Panchito 044™ is designed to incorporate bore sizes from 85.5mm to 94mm. With the added combustion chamber material we can machine your Panchito 044™ heads to the depths necessary for high compression applications."

Thanks Dan!!!
Another quick question, while I'm at it, it was recommended to put on a sump. Any suggestions?? It looks like one with the lifetime filter in it would be the ticket as I was going to put an external filter on it too. I was just trying to keep it a little higher off the road.

Sat Jul 02, 2016 12:02 pm

Personally I don't like Oil sumps or external oil coolers! I don't like engines that need them either. So someone else will have one for you if that is what your wanting to do. A well built, full flow remotely filtered, properly camed not too big of VW Type 1 engine with the OEM Dog House fan shroud doesn't need extra oil cooling. I would spend the money on Counterweighting and Balancing the crank and flywheel and clutch and maybe some nice H-Beam connecting rods.

Sat Jul 02, 2016 12:22 pm

Well, either fortunately or unfortunately, the engine is already built, in and I'm running it, and I'm not wanting to pull it down - at least not during the summer. I have a 69mm balanced and counterweighted and a 12# balanced flywheel. No H-Beams tho. Just remaned rods.
Maybe just the external filter would be fine. That was my original thought. I just thought a sump would help cool a bit. I do have an issue cooling too. The (main) problem seems to be the high gear (3.88) and low RPM's going down the highway (2400 at 60mph) is the issue. But I'm not into changing gears either. Plus, it did the same over heating thing with my swing axle and it had 4.35s. Unfortunately, any problems that require major motor or trans pull downs just aren't in the cards right now. (bummer, I know) So I am looking for alternatives.
Thanks for all the help!!! I really appreciate it!!

DEEP SUMP . . . According to Gene Berg, you should have a sump. BUT . . . notice no mention of it cooling your oil . . . http://www.geneberg.com/article.php?ArticleID=229

STOCK CONNECTING RODS . . . I used them in every engine I have built . . . and even though I beat some of those engines pretty good, I never had a con-rod problem.

As for tearing yer engine apart, no.
Some new heads and re-jetting those carbs and you will be good to go!

Sat Jul 02, 2016 11:09 pm

I have used Empi, CB, and Berg sumps All of them are fine. Make sure you clean them out REALLY well before you use them.

I have both an EMPI 1 1/2qt sump and a 3qt. The 3qt came with better mounting hardware but I bought it a couple of years before I bought the smaller one. Don't know, maybe they all come with the crappier hardware now. :?
