What heads are you starting out with? It would take a pile of shaving to get 11:1 out of a set of large chamber smog heads. There is no reason to run high compression in a street truck.
Compare what it is going to cost you for the head porting with new valves and springs, and you may be better off starting with a set of the Edelbrock heads. I agree that a Performer RPM intake would better fit the bill.
It would pay to have the block sonic checked before you go .060 over. Thin walls make for heat on the street.
I would first make sure that the truck is geared decent before spending money on a converter. Glass packs add 2 seconds to your 1/4 mile time :). If you want a low restriction muffler, go with something on the line of a hooker straight through design which will cut the noise down, but not let everyone know how young you are :).
