Head Pressure?


are you talking compression? it should have 125psi to 135psi depending on the tester you use. as long as all 3 are within 5 lbs of each other, you are fine.

if you have a thin headgasket in place the compression will be higher than stock.

When you seperate the stock gasket into three gaskets, what compression would each gasket give?
