I did on a 548 last week with the same heads and quench, same style piston. Power didn't go up, actually lost some at 36* and egt's only dropped a few degrees. Most of these guys fill up on the road with 93 octane which I prefer, more additives etc. less chance of getting a bad tank of fuel. So I don't mind running a little hotter plug, a little lower air fuel and the temps fall in line. Without fouling plugs or poor idling.

The 548's cam is a bit more conservative. It was originally selected for a boat with reversion issues. It made 635 and 660tq
