Lets see how close I am before someone chimes in with a more accurate figure or if they have the desk top dyno. This sounds like a good combo so I would say that you are pushing 350 plus HP depending on what kind of heads they are. They aren't the later 71 + "smog" heads since they are 64CC heads, so they should be decent. It's hard to tell from combos like this on how the parts work together unless someone has actually dyno'd the combo, but the best estimate is the butt dyno and grin factor when you punch it.
