dude get a lightweight flywheel and a clutch!! car will be quicker out of the hole and rev faster.
Put some 14's on the front of your car.
also use 87 octane gas and a new set of plugs and wires.
the exhaust will help also.
cams dnt help too much unless u got higher compression to go along with it, and they arent cheap.
u can get the head posted and polished but thats not gonna be cheap either.
