How do I identify Dunn cylinder heads on my 1995 ZR-1 Corvette?

Wrong forum to ask, this is C6 Gen & you need C4 Gen.

Look at the side of the head. There will be an imprint that says Dunn. It’s located top, center and on the outside of the head itself.

My car is number 151, which I find interesting. I did not think there were that many cars produced with the Dunn heads.
Pictures attached. Sorry they are backwards. It was easiest to take the pictures with a mirror.

the 93 last run of engines when Birmal heads ran out the Dunns castings took over

some engines had one of each as the cutover occurred

they have some nice improvements from lessons learned and seem to flow just a bit better and help out with the chain rattle on startup with improved tensioner
