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?

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.

At 60.5 cc they were milled .55.Sounds like the heads Lingenfelter did for GM.
