It's not a race motor, I would think 150/160# would be plenty for you. If you want to run less expensive fuel, just get a new set of domes that will work for your setup. 

It has a high compression cool head on it. Im ok with running race gas, I just want to know if I dont have another option, can i run 91? And the engine isnt completely broken in yet
