I carefullythe piston protrusions after cleaning all surfaces and measured the following piston protrusions using a magnetic base dial indicator accurate to 1/10,000"
#1 0.037"
#2 0.038"
#3 0.041"
#4 0.036"
These numbers require a 3 hole head gasket per the Bently. They are not perfectly even and Bently has no spec for it. Does it lookOK?
