Lol, I whooped my friends LT1 Firebird that had bolt ons with my 3.4 setup.

Rockers are a good choice if you dont plan on camming, or using a little cam with 1.7 rockers.

Could always get your S/C ported inlet/outlet and drop pulley size/retune to be cheap, and add some power.

IMO, Heads, cam, IC, then just run the belt on the hub.
