I was just curious if those more experienced engine builders would think if I'll have a problem with this setup

351w block
flat top pistons with 4 2cc valve releifs(deck milled)
62cc world windsor sr iron heads (milled from 64cc) with 2.02/1.6 valves
10.49:1 cc with a .039 head gasket

the cam is a lunati 41008 solid flat

290/300 adv dur.
249/258 dur @.50
.54/.544 lift with 1.6 rockers
I have 1.72 rockers so my lift will be .581/.585
108LSA with a 104 ICL

There is no absolute way to tell except to mock it up and measure it directly. I suggest doing so anytime an aftermarket cam is insalled.

With 2.02 intake valves and that big a cam, yea, you're gonna be close, if they're not hitting already.

With 2.02 valves you're really gonna need a small cam, to not have to worry about the pistons kissing the valves. "If you want to play, you've got to pay" Now on my 331, even with the Canfield heads milled .060, and a .587 lift 228 degree cam (@ .050) I've had no issues with 1.94 valves. Most pistons only have reliefs for up to 1.94's. Only some have them to accomodate 2.02's
