I just can't seem to let well enough alone. Had her on the road for 2 Rodding seasons and have decided to go up on the horsepower. What I had on there were the original iron heads with a little porting on the inlet. stock valve sizes, but with all the Hi-po gear bolted on. Compression was at a stock-ish 9.0:1. Replacement heads are RHS aluminum 180cc. 58cc chambers 2.02 Inlet & 1.6 Exh valves.

The calculated compression will be about 10.3:1, this should make the old girl get up and boogie. Well I hope it will.
