Help ID'ing heads
Well, my 66 is back with a freshly rebuilt 428. She runs AWESOME and I could not be happier.
Alas, I don't know what heads he put on and nor does he?! They are larger so to drop the compression to a more manageable ratio but I can't find any information online to help in ID'ing them. The only marking is a very obvious 7H. I have checked the usual sources and the only ones which might say 7H are even smaller than the stock heads.
There is reference to 6X 7H heads. Is that what is on there?
I will try and attach a pic
