Im almost completed building my heads, port polish, deck, shim sprngs, 3 angle valve seats, manley ss valves, billet push rods, and soon rockers. I already have evt carb and intake and should order exhaust this week. So now that im almost out of everything i can do without cracking the case open. First off the main thing i hear failing in the 35's is cams so im debating on if to do a cam. Next I will replace the connecting rod but im debating on piston setup. The main thing that seperates a stage 2 from a stage 3 is shaved pistons or extreme flat tops. Im leery of doing any work that cannot be returned to stock if performance parts become hard to find. flattop pistons require boring the block, cut pistons dont . What would be the diference in hp from a stage 2 to a stage 3? Also do bps pistons require a bored cylinder or are they stock fitted? Anyone running them and how do they perform?

u can get flat tops for de stock bore

i doubt performance parts will become scarce, being that they were available before surface drives were, due to lawmower racing and go karts and shit

about $1000 and 2.5 mph on my big ass boat.

How about putting what you have together and seeing how it runs.

You may be very happy with the performance from heads, carb, and muffler.

Just waiting on the call to come get the heads then ill run it from there. I know when we do heads on automobiles we use a thred tracer to get all the dirt and gasket pieces out do yall do this on your mm's? any other precautionary measures yall can recommend for installation?
