Educated guess on piston/valve clearance
What kind of room is in there?
I'm looking at the following combo:
Trickflow heads, milled to 58 CC.
.049 compressed head gasket.
.578 intake lift, 230 @ .050, 109 ICL
.565 exhaust lift, 236 @ .050
Do I stand a chance?

Re: Educated guess on piston/valve clearance
you'll be fine...what does your valve timing events look like? that and duration are the "biggest" factors when it comes to P-V-C. Usually when you get to .600" lift and over is when you really want to check it. Whats your valve timing @ BBDC, BTDC etc...? you could do common clay on top of the piston test, works like a charm.
