change the gears first and then think about porting or changing the cam. maybe even bigger than 410's ?

you might not be concerned once the power is where it should be what gears are you running now ? rear tire size ?

porting will increase upper hp but if you have low end problems right now i wouldnt do it.

increase also depends on how well the heads were finished ive seen people not get any gains and seen as much as 90hp on a full blown race engine.

but its all the overall combo that counts
