It should bolt up without changing the heads.
Intake Manifold (Cast Iron Heads) Non- Hardening Sealer 30 ft-lbs.
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
The heads will fit the block, but the vortec intake manifold will not bolt to the old style heads.
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.
ANY year that has a carburetor intake manifold available to install on the block/heads.
on a 2001, with the 3.3, the knock sensor is under the water crossover pipes, which are under the intake manifold. Pain to change. Take off plenum, intake manifold and there it is, on top of the block between the heads.
It is on the back of the block between the cylinder heads at the very top where the intake manifold meets the block
you do not need to remove intake manifold to change valve cover gaskets. intake bolts to the block. valve covers bolt to the heads EDIT: Theirs some clearance issues but you can maneuver the valve cover out.
Yes, however, in 89, Chevy started to update the small block, and came out with the SB2, or first gen., Vortec, and redesigned the cylinder heads. One of the changes they finally made was to change the head angle, in relation to the block deck. This also changed the intake manifold/cylinder head, relationship, making this intake non interchangable, with the SB1, or the standard heads.
No, the head gasket is underneath the heads where they mount onto the block. Your intake manifold is bolted to the top of your heads. Some motors have coolant that circulates in the intake manifold ( I don't know what year or make your vehicle is ) so I would check my shop or repair manual. There could be a crack where the coolant flows through your intake manifold or one of the manifold gaskets may need replacing.
There are 2 of them. They are sandwiched between the heads and the engine block. In order to replace them the intake manifold and heads must be removed and exhaust manifold disconnected. Always replace both of them on a V6.
An intake manifold gasket is a malleable material that is set between the air intake manifold, the cylinder heads and the block in a gasoline powered internal combustion engine. Intake manifold gaskets prevent leakage of air or the air-fuel mixture by sealing the gap between these various metal engine parts.
