[bmw] e30 head gasket
What is the purose of the thicker head gasket after having the head
resurfaced? A used head was resurfaced to maximum spec for use on a
rebuilt m20b25 (325i) with a 276 degree by 10.2 mm lift cam, overbored
stock pistons. The machinist pointed out that there is an optimal
clearance between the piston dome and the head which will facilitate
combustion by squeezing the mixture into the area around the sparkplug.
The question is will the piston be too close to the valves and head with
the standard gasket? I don't want to decrease the compression with the
thicker gasket.
Greg with a project too
