More compression for 2f

Just wanted to know if anyone knows the valve to piston clearance in a 2f (valve open of course) so i can get a 2f block decked so i can up the compression a bit from the lazy 8.1 to 1 , to closer to 9.5 or 10 to 1. Or does anyone know of any company making high compression pistons for the 2f. Thanks.

Cant you put a F head on a 2F and get increased compression figures?

No the F head has an external oil feed I think to the head if I recall correctly.

Maybe its the F155 head then, from 1973?

I'm pretty sure the early 2f and f motor had a larger combustion chamber.

Also had domed pistons, later had flat top pistons.
