Just a quick question everyone, how big of a cam can I run with GTP Stage 2 heads milled to .015 without any Piston to Valve Clearance issues? They have 2.02 and 1.57 valves. I really dont want to have to flycut but I guess I will if I have to. Any help would be appreciated. I was looking at some TSP cams and some Futural cams and this cam will be at 114 LSA.

Thanks again!

well you should always check ptv clearance but there are people running the same type of 5.3 heads milled ~.010-.015 w/ 2.02/1.55 and 2.02/1.60 valves with cams in the mid 230 duration (FM13'ish). w/ no fly cutting.

Gomer just finished up an install for a guy that has 5.3 heads w/ 2.02s milled .019" with a F13 cam and it was fine.

i read the posted article jrp posted but really don't understand the first part about checking half of valve pocket and what not. Somebody care to explain in little words and speaking slowly?
