318 horsepower

It is a 1987 318 I did look at the head casting numbers and they are 302 castings and from what I hear that is a decent head. You said find out how far down the piston sits in the hole, ????? Just how do I go about that? Is it as simple as measuring the distance from the top of the head to the top of the Piston at TDC ???? If so, what should I use to measure it???
