I run a 125hp shot with a 190lph pump, 24lbers, AFPR, and aluminum heads. I keep my timing at 12 degrees and run one step colder plugs. I've also got an Accel ignition system, and distributor, all in all, just to be safe. Had about 6 bottles worth through it this summer, and have around 40,000kms on the motor without any problems.
Exgmguy is absolutely right tho, to get away with more timing, aluminum heads are the ticket. Even though I must say 15 with a 150 shot would scare me a little, its all in the state of tune, ie. good gas, plugs, ignition etc..
