The Sr20/Sr22vet thread

Oh I got the concept of shimless, just wasn't sure how it was acheived in this head as there's a few ways to go about it.

What Cams are you guys using in the US?

184ST's are easily the best all around cam and what I'll always push. I've never seen them not perform well unless someone was looking to make over 800HP or so.

Verdict is out . Apart from Bill Washburn and the one time he had a shim pop out on him, it seems only the drift/hardcore drag guys have this issue (for obvious reasons).

Shim it to factory specs and see how that works out. Do not forget step 5 when shimming; you can only shim 1 rocker finger at a time (you can do 4 valves per intake and exhaust to make it go quicker).

Me thinks it is a great idea but not a necessity. But if you have the head apart, whats another 5-700 dollars right?? Yeah, its called the VE slippery slope logic

I've only run BCs and not for long enough to know if wear was an issue with those.

Maybe I'll just run the Kelford stuff then I can blame them if it wears

What's the shimless valve setup?

I think the mixed reviews (which are somewhat few and far between) are the 123lb supertechs. Meh, run what you can get your hands on.

I have one of the few sets of the Kelford Behives at the moment so we will

Meh. P11/P12 cams work for 70-80% of the builds out there in all honesty. At close to $1000 USD, the price of entry is not worth it to me for sub 500 WHP.

But again, like everything it is just my opinion. YMMV

I recommend you lay out your power and usage goal and back track from there. Eliminate things you do not need to make your power reliably. Just realize once you start cracking 500+ WHP, costs rise exponentially, not linearly.

Not a cheap head, but thats because people end up sliding right down on the slippery slope and just continue to plunk $$ on items which are nice to haves but not necessarily needed (or they are going for big power, which is an automatic do not pass go and YOU spend 10,000 dollars ).
