Another thing, get some 1.7 rockers for your heads, no matter what kind of porting you do on those stock heads, the 1.7 ratio will take advantage of the larger volumes of air, using stock cam.
Also before many mods, most people strongly believe you need subframe connectors, you cant go wrong with those two mods above, combined with slicks should give some good gains.
