I just saw this posted on a Facebook forum concering 186 heads for a 69 Z28:
"If they are true DZ 302 Head's their are 3 place's that they can be stamped DZ 302 (1) inside the head where the valve cover is (2) at the water jacket of the head where the piston is (3) at the face of the head is where they stamp them at . They have the big 202 valve's"
I do not believe this to be true, but I thought I would put this out here for the experts. What is the consensus on this?
