I thought I should check clearance of my cylinder heads to valves and pistons. I remember Ol Ron suggested using aluminum foil balls stuck on with grease. I have Edelbrock 1126 heads, and checked clearance without a head gasket that I figure will add about .07" to my clearance. The valves all measure between .05" and .07" clearance without the head gasket. The pistons at the dome consistently measure .03" again with out the head gasket. This should translate into piston to head clearance of .10" approximately. and over valves of .12" to .14". This seems adequate to me, and thought the foil balls worked well. Any thoughts?
