Putting a dyno 356 cam in predator hemi and just got through checking piston to valve clearance and came up with .070 on intake valve and .075 on exhaust valve. This is with stock valves and springs and lash caps with zero lash and no head gasket. Is this okay or too little or can i mill head .050 and put .010 head gasket on with .003 or so valve lash and still be okay ? ? Gonna still do mods on valves , springs and push rods but kinda worried about close tolerances on valve to piston clearance.
