[355REDNECK]

are these heads considered vortec heads

[7d9_z28]

need to be a bit more specific, but if you are referring to 88-95  gm sbc heads with tbi, then no.

[OHEARN.2012]

vortec heads are vortec head they come off vortec motors

[frdzila]

To the best of my knowledge tbi=1987-1995 heads vortec=1996on heads.

[7d9_z28]

Since vortec motors use a throttle body, im sure they can be mislabeled...

I dont think fast burns were used on factory motors? i could be wrong. thought they were only on the crate motors like the zz4 and such

[7d9_z28]

and IIRC, the fast burns are basically aluminum vortecs....
