Regardless of the block, you have to use Vortec heads to use a Vortec intake.

the fastest way to tell is if the center intake bolts are not there.the vortec heads that everyone wants for performance have no center intake bolts.
Can you replace a pre 1996 tbi engine with a vortec long block and use your tbi intake and tbi?
you can as long as you use your TBI heads if you want to use the vortec heads with TBI you will need a special intake manifold or a carb manifold with a adapter to mount your throttle body to the carb manifold heres some more info TBI heads will mount to the vortec block TBI intake manifold has 12 bolts vortec intake manifold has 8 bolts

Will a 89 350 bolt up to vortec heads?
Yes an 89 350 will bolt up to original Vortec heads. However, Vortec heads have an 8 bolt inatke manifold that is different from the standard 89' intake. Its worth mentioning that the intake manifolds changed in 1986. Prior to 1986 all intake manifolds for a sbc had 12 bolts. These 12 bolts all secured the intake to the head at the same angle. In 1986, or primarily in 1987 the intakes 4 center bolts were changed to a steeper angle. With the introduction of the vortec head came a new 8 bolt intake eliminating the 4 center bolts. If you plan to use Vortec heads on any V8 be it a 305,327,350 or bigger, you will need a Vortec intake manifold as well. You can also buy an after market intake to run a carburetor on a set of Vortec heads in place of the TBI injection.
Will the heads off a 97 vortec fit of a 88 350 block?
Yes, they will fit, and increase torque by a good amount. However, the Vortec heads used a vertical intake bolt design, so you will not be able to use your intake manifold. Side note on the vertical intake bolts, you also need to get Vortec specific intake bolts, because they bottom out in the heads to stop from overtightening and seal better. All in all, vortecs are a good purchase, if you have the money for a new intake manifold. Edelbrock makes some great ones specifically for vortec heads on older engines. look into it. hope i could help.

Will 1999 vortec heads fit a 1990 350 block?

What does vortec heads look like?
they have valve covers that bolt down from the center, with heart shaped chambers on the 5.7 heads and no center intake bolts. the 5.0 vortecs are similar and not as good but still will flow really well compared to most heads and the old camel backs or humps.the fastest way to tell is if the center intake bolts are not there.the vortec heads that everyone wants for performance have no center intake bolts.see link below
