Thought I would share what I measured on my build.

C59A
Stk crank
0.060” over (Egge pistons)
C7RA-A cast iron factory Ford heads
Felpro head gasket - 0.055” thk
NGK sparkplugs
Block and heads were skimmed (not sure how much), but it was just to “clean” them up
Heads were tightened to spec

Head to piston clearance - 0.073”
Sparkplug to exh valve clearance - 0.128” (valve closed).
