Cougar is right, if you’re not sure what you want then the best way to find out would be to go for a few rides in different set ups. And, if you do decide to go with some heads then after you choose the cam you want, post up the specs for it. Static compression doesn’t really mean shit but your dynamic compression ratio is very important and I’ll need your cam specs to calculate it. From this you can find out what size chamber the heads should have to give you a DCR up around 8.5:1. They come in many sizes and just randomly selecting one could leave you to low and leave hp, torque, drivability and gas milage on the table…to high and you could run into some major knock problems and no timing advance in your tune. And depending on your cam you’ll have to pay attention to the piston to valve clearance.
So when you pick out a cam, post up the specs (I&E durrations, lifts, LSA, and ground in advance).
