GMC 302 Big Port Head - 09/04/06 04:06 PM

This is a cross section view and is an actual 302 head that was sliced with a band saw through the intake and exhaust ports giving a nice view. Many wonder what these things are really like inside so here's a shot of inside of an actual 302 head.

Here's another view of it:
This gives you a sense of just what the inside of these heads really looks like!
