Will my ASA 226/236 525/525 110 LSA work with some PRC 2.5 5.3L heads (unmilled/2.04/1.575 valves) without having to flycut? This setup is going on a stock bottom end LS1. What gaskets to use? Need some info asap!!!

 

It seems like it should be ok with only 525 lift. Put in some .040 gaskets if there's enough ptv clearance.

 

should have plenty of room

 

Thanks for the help guys. Im actually looking at another cam now. I was going with an MS3 but the heads werent setup for it. I bought them used. So now I need to find a replacement. Any ideas? I don't want to flycut either!!! What about the 228R cam from TSP?

 

You should contact TSP, They are super friendly and quick to respond.

I am waiting on my 224/236 @ .609/.607 111 cam to come in. Going with the PRC 2.5 5.3 heads also with the larger valves but originally machined for the MS3. I milled the heads 0.020" and TSP "Thought" I should be safe with PTV. But I am going to measure it as soon as my cam shows up, I'll post up my findings when I am able to.
