Had the high compression (10-1 with stock pistons) Rev-Tec heads on a 1991 FLSTF 80 inch running a RevTech 2-1 exhaust Rev Tech Carb and the Andrews EV-35 cam ,made 87 hp. Had also run the EV-7 but had no lower end(no suprise) but made 4 more hp on top. The EV-7 would work fine for 100 inches
Rev Tech evo heads any good??
