Regardless of the block, you have to use Vortec heads to use a Vortec intake.
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
no you cant this is a different style and requires that style of head
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.

The word 'vortec' is the name of the cylinder heads used in Vortec Model engines in the year 96'+ The engines that use the Vortec cylinder heads are the 4.3L Vortec, 5.0L Vortec, 5.7L Vortec, and 8.1L Vortec. They were only put on Gen I small blocks. If they are any other size Chevy engines and still retain the Vortec name then it's purely a marketing name, the same goes is it is later than a Gen I engine. For example the new 4.2L I6 from GM retains the name Vortec, but it does not actually use Vortec heads as these heads were only made for OHV engines, and the I6 is an OHC engine. The Vortec heads are based on the LT1 and LT4 head after they were discontinued along with their reverse flow cooling design. It is simply an effect made in the head similar to a vortex to better atomize the fuel and air intake charge when entering the combustion chamber, it is not a different type of motor.

You can put the Vortec in it if you have the wiring and ecm to run it. or you could use the Vortec heads and an aftermarket intake and really wake up your engine. The vortecs use a roller cam.
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.
If you attempt to put a vortec engine into a vehicle with a NON-vortec computer, you'll have more problems than you care to deal with.
I am assuming that this is not a vortec engine?.......If it is a vortec, they use different angle bolts securing the intake to the heads..........and you will have to get an aftermarket intake to run a carb........If it is not a vortec engine..........go to a junk yard and search out a cast Iron unit form a van..........they are most common........Of course it will be of the spread bore pattern and if you choose to use a holley you will have to use an adapter plate..........If not, a quadrajet will bolt right to it..............
Not without A LOT of modification.Answeryea they will fit but you will have to switch over to the newer style valve covers because of different bolt patterns AnswerYes they'll fit, but like answer #1 some modifications. Two intake bolts are angled different, than the others. You'll also have to change valve covers. I have a set of LT1 heads with 202 160 valves, ported and polished and seven sixteen screw in studs and a hv1000 brodix intake and its fast. So it will work. also the heads have to be drilled for the water to flow through the intake. three holes alltogether(2holes drilled in between center exhaust ports below spark plugs on each head. Not mentioned above is the fact that the LT1 heads have to be welded in 4 places or water will flow into the intake valley on a gen 1 block. GMPP has a carb manifold with provisions for a distributor for a LT1 that I used on my LT1 head on Gen 1 conversion. I also drilled and tapped the front of the heads for water return.
On this engine I recommend you use an AC/Delco filter.
