I just pulled the intake off to investigate the oil consumption issue and found my intake gasket is most likely the cause. Very oily and most likely leaking into intake ports. Can anyone identify the pistons and rockers I have. Am going to maybe change the heads ( casting 333882 ) did some research and found they don't seem to be very good. Pistons are domed a bit just below valve reliefs, about 1/4" above deck when at TDC. Also the rockers have numbers on the top side opposite the valve. Not sure what they are. I know what the 1.5 is but on the other side there is also a number. Most are 5 but there are some 2's & 6's also?
