Heyas, been kicking round an idea and was looking for some outside feedback. Ok got a stockish 350 makes decent power, no clue what the cam is, my guse it was swaped sounds a little lopey, but mild. Planned on throwing a few parts i got laying round on it for some summer fun, don't wanna drop a lot of $ into it as I have higher priority projects.

has
-performer intake/ q-jet
-c4 corvette stock headers with 3" y pipe
-mild cam

got laying round
-670 holley avenger
-roller rockers
-underdrive pulleys/alum water pump
-good wires/coil/modual/curve kit/adj vac advance

I got plenty of other stuff but more racey or I don't wanna put it on this engine So My real question is I got these Sportsman II heads laying round no real plans of useing them in the future. Ran em on a close too 500hp engine a few years back and they have sat around collecting dust. I know they worked great with a 750dp, vic jr, 3500 stall, big cam, long tube headers. I'm just not sure how they will fair with the setup I got. I want the most power I can out of this motor with stuff laying round, but I'm just not sure if the heads willl hurt more than help on a mild setup. I know I should swap the cam but I'd rather leave the stock heads on before I divert funds from another project.
