Not on the head gaskets.
Remove carburator then intake manifold then cylinder heads
They can if the heads are cracked ,are the intake manifold gaskets were put on wrong when thay were installed. The heads themselves if thay are good heads will not cause overheating. You cannot put the head gaskets on wrong on a small block Chevy engine.
head gaskets??? warped heads? did you have them milled?
call your Chevy parts man at the dealer and he will be able to look it up for you.
Change the pistons, or change the cylinder heads, or mill down the cylinder heads.
on what part of the car?wheels,heads,intake manifold...you must be more specific!
From 1996 to late 1999 There was a problem with the intake gasket design on the Vortec engines. They have sents redesigned the gasket and now it does not leak as often. Intake Gaskets leaking is a common problem. Now the only time you have a problem with the heads is when the engine is over heated, and I mean HOT. Then the heads warp and the head gaskets leak or blow. Chevy just don't have problems with the heads on the V6 and V8 engines.
IF BOTH HEADS ARE REMOVED ABOUT 900.00
usally about 8 or 10 degrees BTDC will work fine to get it going.
Yes, the distributor has to come out to remove the intake manifold in order to remove the heads.
