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.

The 85 intake manifold won't work with the 90 heads, so you will need to purchase an aftermarket intake if you want to use a carburetor or use a 87 to 95 intake if you want to change over to TBI.

the heads should fit as long as your not trying to put them on a big block

User Avatar

there is no adapter. vortec heads were cut at a diffrent slope than standard sbc heads. you can swap the heads on the 78 350 for vortech heads or get a multipoint fuel injection intake for a 85 - 95 350. you can get the intake from summitracing.com You will have to swap the heads and the intake

350 heads will bolt to the 400 block. They will need to be drilled for the "steam ports" in the 400 block.

User Avatar

Depending on years that you are swapping around....yes. The 305 heads will raise the compression of the 350 considerably. However, the intake valves are a lot smaller than the 350.

will 1995 Chevrolet 350 intake fit a 1997 vortec heads

User Avatar

yes! depending on the block. ie. a 350 or 305 will work with newer heads and intakes. as long as you have the correct gasket. the heads can not be reverse flow. they will not work without modification.

User Avatar

Yes you can but you will need to modify the bolt holes in the intake manifold. The TBI intake 4 center bolts, 2 on each side will not line up with the heads. Must drill them out just a little.

User Avatar

Yes , but you will need a tbi intake to fit vortec heads if you retain the 90 TBI fuel system.

User Avatar

Depending on your intake system, you should be anywhere from 360 to 380.

User Avatar

yes all sbc manifolds will fit, when you get to cyl heads then you will have trouble since most aftermarket are for 350 bore which is larger

User Avatar

yes they will fit, but you will need an intake manifold compatible with vortec heads if you plan on reusing the carburetor

User Avatar

yes, you can use those heads. the block does have small changes to it but no problm will occur

350 chevy with aluminum heads and intake carb and headers weigh

User Avatar

yes ,I have change one out with a old 350 it had lot more power . I used the old heads to with vortec intake you have to slot the four bolt holes .but it will work.

User Avatar

Yes they will, But you will have to drill the 4 center bolt holes out in the 88 intake to make it bolt up to the 305 heads. I don't no why anyone would want to put 305 heads on a 350 engine, The 350 will never run like it did before.

As long as the 350 block is under the year 1986. Then all of the external engine parts will interchange. The heads and intake will also interchange. The CRANK AND RODS AND PISTONS WILL NO INTERCHANGE.
