someone can correct me if I'm wrong, but the only real way to tell that I know of is checking the casting number on the back of the head.

my gt-40's have GT stamped on the heads and the p's have 4 bars if I remember correct , also the p heads require the p headers to work because of the spark plug angles

There will be bars on the ends of the heads and GT will be between the valve springs too.

3 bars on front and rear of heads plus it should have gt on at least one of the outside corners
