I think I might hate you. I know I will hate you if you tell us you paid 200 bucks for it.
I will check for the "H" on the head in a few minutes.
I have been watching project banana split on Detroit musclep on television and they put disc on the front of their 49. I think this would be a great improvement. They also added a dual master cylinder from a C3 vette in the stock location and it worked great they said.
I may have to rebuild the stock brakes at first but hope to go disc on front later on
I was doing some reading and the head has 7HA 6050-C2 on it which may be the G series
