space between valves and piston
I was wondering how much clearance there is between the vlaves and piston in a Ford 300 I6. I'm in the middle of a full performance rebuild and want to know how much the machinist can remove from the deck of the block and the head when he's straigntening them out. I'm planning on using Clifford Performances' oversized valves that measure at 1.940'' intake and 1.6'' exhaust. I'll also be using their piston heads if that matters. Thanks for any replies.

thanks slammercb. I'll tell the machinist where my maximums are. I was thinking that If I stayed away from the thicker head gasket that I might get a little higher compression. Figured it was worth a shot. the spring test sounds like a great idea, but where would I get the low load springs?

You probably won't need a thicker head gasket. More of a suggestion if your p/v clearance becomes an issue.
