I have the following

95" jugs
SE CNC PORTED HEADS
SE GASKETS
SE PISTONS (the ones recommended for the heads)
SE 257 CAM

Is my compression 10.5? I had thought that it was.

thanks

Compression right?

The last motor I built with that combo. Was 10.2-1 out of the box I milled the heads to get 10.5-1.The factory frequently overates(or maybe it is production tolerances) the C.R. on the S.E. heads and pistons.We allways pour the chambers and pistons and calaulate the true C.R.Not something you want to guess at.
