Swapping to 76 cc chamber heads is only going to drop you to about 11.25 to 1. 72 cc chamber heads will put you in the 11.8 to 11.9 range. Neither is low enough 91 octane for me, however it would run nicely on 100LL. Actual compression may vary depending on if the block was decked and what head gaskets were used. Your not going to know what deck clearence is without disassembly. Sounds like you have some nice heads that you would want to give up anyway. Running Av gas on the street is tax evasion just like running off road diesel. Not making any judgement here just don't take this as an endorsement.
