Default 302 Piston to valve clearance
Any Guru engine builders out there who can advise me on this. I don't want to yank the heads to check this.

I have a Crane cam with 288 total duration, 228 @ .050 and .488 lift with a lobe separation of 108. I want to go to 1.7 rockers from my current 1.6 roller rockers. This is an old 302 with dished pistons, not a newer 5.0 with flattops. So, . . . if I go from .488 lift to .518 with the 1.7 rockers, am I gonna make it???

The heads are Edelbrock aluminum with 1.90 intakes.

thanks
Ed
