some engine questions
OK, I have a low mileage stock 350 short block, roller cam, 1 piece rear main
OK, I have a set of bowtie heads and a set of stock 350 tbi heads
If I go with the bowtie heads, will it run OK with a ZZ4 cam and TPI?
what injectors?(I have a set of 19#, 22# and 30#)
tuning is not an issue(DFI)

The bow ties are small enough of a port that they won't kill torque. They should flow alot better than the TBI heads, but I have no personel experience with either of them, although i've heard the tbi truck heads suck. Just make sure you have the valve springs and the clearances needed to run the .525 lift of the zz4 cam.
22lb'ers should be all you need, but you could *probably* get by with the 19lber's. I'd sell the 30lb'ers for some $$ or keep them for another car, unless your planning on boost or more power later and want the extra injector. Tuning wise (for a stock ecm car) the 22lb'ers would be easiest to tune, but it shouldn't matter for you with DFI.
