Sorry about the late replie just went to my mate unit there and he's got a forged ep82 with the same rods & pistons as mine did a compression test and his is reading 122 psi over all 4 cylinders double checked mine and still the same as before 110 psi over all 4 cylinders if a can mind correctly am sure the the boy that built my engine used a 1.4 mm Antena headgasket does this lower the compression even more ?
