I went AFR 245 with a bunch of tricks in them, you can also go TRick flow as well. Both will have similar results.
Thats because all the head issues have answers, just no one wants to listen to us shops that actually build these cars. They just like to say they know.

Not sure all of the shops know the guide wear answer. Looking at the ported heads that have the guides ground down to a shorter length than stock leads me to believe those shops don't know the answer.

That was my thought as well, but they clearly told me that they will NOT replace the heads nor help with any labor costs.
At this point in time I'm out more than $7000 for a fix that did not work
for whatever reason! Unfortunately I'm far from being an expert, I just want this issue to get fixed and be (more) reliable.

Sorry as stated in the other thread he did not offer any more information about the issue. It's privileged info I guess I didn't press the issue. Rick is an expert at what he does and I trust his judgement more than anybody I know in the LSX community I trust his word 100%.

Aren't we talking in circles here. The thread started on Page 1 by saying that SS valves in Bronze guides on a new set of PRC heads failed prematurely because of a large amount of intake guide wear.
Now people are saying we know the answer and it is the OEM valves. I don't know if I disagree with that statement but this thread is about the OPs aftermarket heads with SS valves.
So again why did they fail? And I may know nothing about head design but I do know the answer cannot be "because they had OEM valves" because they didn't.

If the oem valves are so bad how are Katech builds running so successfully? We also have little to no guide measurements from "the fix". We also have little to no valve valve failures without the presence of guide wear.
Other than secret societies how are these conclusions being formed? Also what is the point of posting "expert" opinions if you dont say who the expert is. Its completely pointless without validation.

Yeah yeah, I know, single case, not enough background info, another forum, humans are capable of dishonesty, yadda yadda
Oh and BTW, they use a Solid Inconel Exhaust Valve on their TT air attack package, so at some point, even they determine that a solid inconel exhaust valve is necessary.

I wouldn't consider this failed air attack head as successful.
