yes hydraulic.So hydraulic cam? You may have said that. Just wanted to make sure you didn't have a mechanical cam.
You can get almost 1 compression number out of a thicker gasket. Cometic MLS gaskets are available in thicker sizes at Summit. maybe even for Fords!
entering all my information into a "compression ratio calculator" and changing the gasket thickness doesn't do much of anything. going from .041 gasket to .060 gasket changes compression from 11.73 to 11.16:1 in my instance.
unless i'm overlooking something.
