I'm about to drop a 350 in my 91 RS in place of the now 151,000+ 305. The 350 is stock except it has Hooker shorty headers. What would be a good pair of heads and a good cam. Also, what about a diff TBI? Would I have to get the computer reprogrammed? OR what about adding a chip and what kind. Thanks everyone!!

the 305 heads you have might be good if they are the same as the TPI high output heads. They would just need to be ported good and get some screw-in studs & guideplates, plus a 3 angle valve job & blending.
I would recommend the camshaft and rockers that I run. You will need aftermarket lifters & hardened pushrods of the proper length (to be determined after assembly).
You can find info on bigger throttle-bodies on this board. I recommend running the biggest you can get along with a good aftermarket intake like an Edlebrock-RPM.
