IM looking for a cheap way to get more power out of my 350. I know a guy who has a wrecked gmc 90s model with the 350 i beleive that has vortec heads. WHat would i have to do to swap the heads and would i gain any power?

Vortec head have a specific intake bolt pattern, so chances (not knowing what you have now) are that the intake you currently have will not fit the Vortec heads. So you'd hafta buy a new intake to use them.

If I remember right, the trucks didn't get 350 vortecs until 94 or 95. They might have but I know they weren't officially called that until 94 or 95. The 4.3 was called vortec since around 93 I believe.
