A set of AFR 185cc heads and a new camshaft will make a world of difference.

If you're running a hydraulic roller, I can recommend some cams that will give you a hp/tq boost without really changing the operating rpms/street manners.

If you're running a flat tappet cam, you will gain a great amount of power by switching to a roller cam.

I don't sell the AFR heads, but I can spec/sell you a custom Comp or Jones camshaft.
