i knew they were the 192 castings, i just didn't know how much they opened them up. very crude calculations and some scaling and i would say these are on the order of a 208-210 high port. i can see the bronze pushrod insert coming through in several of the intake ports.
i would hope the guy who did the work would know what he was doing. he originally worked at TFS. he claimed to have picked up a couple sets of blems as he was leaving TFS, thus i got these castings pretty cheap. also there really wasn't an aluminum option at the time, so the pain of porting iron was just the way it was.
if i hadn't had these heads and had all the work done and gotten the castings at the price i did, i would go with aluminum. i believe the weight savings on the front end would value added!
