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 regular old style 305 heads work on a newer vortec 305 block?

The heads will fit the block, but the vortec intake manifold will not bolt to the old style heads.


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.
