Trying to get the quench set right. Currently looking at what head gasket thicknesses are available. I was hoping to use the standard fel-pro .039 gasket.
With those KB 416s and the .039 gasket that makes my quench .036" (.003 deck clearance by my calculation), which is solid except that it's still slightly more compression than I want.
With a .045 head gasket (which I think was stock) that makes for .042 quench (still fine) and 9.61 static. 9.01 dynamic and 187 cranking PSI with a camshaft closing the intake valve 37 degrees ABDC. Still just a touch higher than I'd prefer, but I could probably get away with it.
Stock numbers are 9.1:1 (advertised at least) static, meaning 8.83:1 dynamic and 182psi cranking, but they also have a reputation for pinging I'd like to avoid with proper quench and ever so slightly less compression.
