The valves might work, but only if you machine a groove in the head's valve seats for 1/16" "O" rings.
CUTE
glad you smiled.
I have been checking around and looking ino Charles and Jakes SDS injection systems I noted one beetle with 44 x 38 valves So I did get that answer But Im sure I will still need thicker ss exhaust valves and a valve guide change But to follow in the milage motor concept smaller intakes of 40s, that means a closer to stock 1.7 head build to get smaller intake runner but the exhaust still gets opened up.
That 76 beetle with The SDS is showing promise, however Im a little puzzled over the absent timming retarder and and knock sencor.I know Jake swares by the Mallory dizzy. But with what i have seen done to a old robert bosch dizzy Makes me think its only a matter of time before the mallory gets a minor internal upgrade to control timming. Im thinking this is a OBD-2 system
If im not mistakin Streat Performace offered something simular That was lap top programable while on car with more tunablity it even copensates for altitude air pressure.
Now 2 questions remain .
Are both case halfs of my t-4 the same deck height. and if not would it be better to start fresh with a T-1 aluminum case a 74 sroke crank and a set of 96 t-1 nickies. my 1.8 has a diffrent crank.and would also have to be done over A new aluminum case is more cost effective. even if I do have to buy the 911 shroud kit.
Charles shot down my idea of the Scat split heads and said they will not run cool enough. I will talk with a Scat tech tomorrow and if this is confirmed I will have to diffrent gettig a T-1 performance head set somewhere near the 1.7 runner size that can except that much porting on the exhaust side . That will be a real pain BUT Im gona try it O rings or not.

Scat knows less about their product than anyone.... The split port heads need no less than 10 design chhanges before I'd even think about using them again...
The cooling is just one aspect that isn't promising with those heads. You'll see the others if you decide to use them.

Yelp Confirmed on the heads. You would think they would want to improve it before selling it.Thats only good for drag racing. And they Need to specify that.
I have also ran into a debate here at home on my 3 possible configurations the 2054 94 jugs x 74 crank a milder setup.
OR and the 2143cc 96x74 setup One of my friend thinks I should go with the bigger with even a longer 76 stroke on the third one. But Im concerned about the head temps getting out of hand, Even if all 3 versions are setup for 8.25:1 compresson . The 2 larger versions. are borderline. Unless you run a water cooled head . And I know even less about them. and how they would work in a Nickie envirment.
Thank you for your help Jake.

I got another call form Scat today.At this point. Im not going to repeat what was said to me . but the facts are disturbing. This just gets wilder and wilder.
Now lets get back to those turbos.
We have and are still discussing that posibility. but that brings on lower compression issues and different heads. lower boost, bigger wrist pins,, so forth and so on. I realy dont that kind of power in a street car. if it can take some moderate revs and put out 125 hp or so thats good enough to maneuver in traffic, and pass a car safley.
I have a drag racer freind that big into turbos. he that has a civic that has done high 4s at the track. I still say thats just looks wrong, and weard to watch.
A NOTHER IDEA MAY COME TO LIGHT.its too soon to say at this point but a T-4/ T-1 Hybrid Block is in the works buy a local racer,How about a 3.8 four cylinder, rummered to be be named the KING CASE now that is unthinkable. every part will be over scaled. and custom made, Sounds inpractical and very expencive, But I want to see this one at the track. Is bigger? better? Time will tell.

Looks like If I get a roller cam and lifters It will have to be made by someone here in my area. I have discussed this with the guy building the 3,8 Vw engine . He wants my old cam for a base line start point to compare to other known solid and roller cam profiles that are compatable my engine spec.s He is no making any promises. to how good he can get it But he said he had a good Idea of what will be very close.
I miked my cam and tried to degree the duration I come up with a ,278 dur. and .410 lift But thats not a confirmed spec, this s a old mic set and they can be off as much as .10 tho
That does not matter, It will have to change some to adapt it o a roller profile anyway
The case halfs dont have matching deck heights and it shows at the top of the clyinders with the pistons being a little differet clearance at TDC. I set it back together to comfirm it .
Again this Helgerson fella made a mess. I want Ray to see that also. He may be able to correct the deck on one of his machines.
OR He may suggest to have the Nickies cylinders cut to correct It

When he suggests cutting up a set of Nickies to adjust for deck height; hand him a fist full of O-rings, grab your cylinders and run . . . . fast.
I am not afraid to try anything. Now Im old school back when they still used the paper gasket at the case end. been there done that But always a stock rebuild.
I am getting a bit skiddish over that trio of fellas .
I've had trouble with John Conley before , Then some of the commits from Jake set of red flags and I felt Charles was the best of the three.
I dont Know Anymore and I don't care.
I nearly got stuck 20 years ago with a bug with a lose head comming home from the beach. I went through 8 Quarts of oil. Pulled the valve cover 3 times to snug what I could get to Just to get home. I still think the O rings would have helped and they would help now.
I recase saved that side of the old bug engine, lighlty cleand the grove in the head then removed some material around the valves to compensate for the compresson change. and run the heck out of it for 6 more years.
As you can read this fron the top. I never said that they have not inprove proceedures from the early days and I still dont like shimming a engine.and would never advise it. It is not a wrong proceedure and IS a commom practice BUT NOT A personal Preference
