stock ones suck and a 3 inch h-pipe on a stock motor is overkill..it really wouldn't benifit you much.....I picked up 2 tenths on my 85 with a previous motor whenI went from stock to equal length shorties

They will help out. I still need to pick up a set to complete my exhaust setup. I am using stock H.O. headers also.

Yes it will help anything that is less restrective on the exhuast within reason will be good for flow. The stock headers have huge crimps in them near the flange that no after market headers should have.
