Which Heads To upgrade to on 91 Z28
I'm wanting to upgrade my heads on my 355 TPI from the stock head without putting a different cam. I need some feedback about Vortec's, Dart.s etc... What is the best set-up to get around 300-340hp out of my car ??? Thanks for any help with this.

Port the stockers and spend the saved cash on a Stealth Ram and a cam.

Junk those stock heads and get a set of Trick Flows.

Or throw on a set of used Vortecs, small cam, and Stealth Ram for about the same price.

Fast-burn heads and a SDPC vortec TPI intake. The heads allready come with upgraded springs, they are aluminum, and the 62 cc chambers will bump compression up slightly.
