AFR cylinder heads

[Killercanary]

I run the AFR 165's on my stock bottom end. I also run an Ed Curtis (FTI) cam. It was close, but I am safely running .546" lift with 224 duration on the intake at 500. I am running a thin .035 compressed gasket though which makes it even closer, with a standard gasket, I would have plenty of room. The only heads that do not require piston notching with 2.02 valves are the TW due to their valve positioning, and the "new" holley systemax heads... the valves are recessed quite a bit and work fine. now as it was said, all motors are different and its obvious from the post above that some are getting away with it. Just make sure to check the piston to valve clearance with checker springs in the heads, if you don't the heavier springs in the heads will bleed the lifters off and give you false readings. Hope this helps.
