Piston / Valve Clearance ?

I'm using LS6 heads milled down to create 60.5cc chambers, stock was 64cc.

Will I have issues running a 222/222 .560 cam?

TIA <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Piston / Valve Clearance ?

So about a .035 milling of the heads would you say?

You should be OK with piston to valve clearance with that cam. I know when we have gotten around .580"+ with duration numbers near 228 we flycut the pistons in the car. You should always check anyway especially if its a cam that has not been used widely before.
