Some have aluminum engine blocks and/or cylinder heads, many of the sensors, intake manifolds
Yes, You have to remove the intake to get the heads off.
You will need to remove the intake and the exhaust manifolds and then you can remove the heads to replace the gaskets.
Remove carburator then intake manifold then cylinder heads
Intake valves are in the cylinder heads.
Yes but you would need to do a lot of work like removeing intake manifolds,heads,exoust,ext... Not for the inpatient
Real simple exhaust camshafts are the camshafts nearest the exhaust manifolds ( outside if cylinder heads) intake camshafts are on the inside closer to center of engine.
On the very top of the engine there is a intake manifold and the intake gaskets go between the intake and cylinder heads.
Yes, however, they both take different intake manifolds, so you will have to transfer the intake, as well.
You must label and disconnect all plug wires and other wires in the way of getting to the intake manifold, valve covers, and head/heads. Then you disconnect the air intake/plenum, and intake manifold. Then remove the valve covers. Then remove the manifolds and the head. Do not attempt this without a Chiltons or Haynes book/detailed instructions, unless you are a certified mechanic.

A bare cylinder block does not contain any other parts. Assuming it is an internal combustion crankshaft/camshaft style engine it should have the following:cylinderscrankshaft journalscamshaft journalsmating surfaces for necessary components such as cylinder heads, oil pan, exhaust and intake manifolds, and etc.drilled/tapped holes for the necessary fasteners (bolts/studs)other holes/passages as neededNote: Cylinder heads usually contain the exhaust and intake manifold mating surfaces.
You must remove the intake manifold, disconnect the exhaust manifolds, and then remove the heads. This is a major repair that takes skill and knowledge. Unless you know what you are doing this repair is best left to a professional.
Can you bolt on earlier heads/intake/exhaust manifolds.. from a 1970 Pontiac 455 to this 76 455 engine.
Begin by removing the valve covers. Remove the cylinder head bolts. The cylinder heads will come off. Reverse the process to install your new cylinder heads.
It is located under intake manifold between the cylinder heads.
In the cylinder heads.
this is a mechanics job you have to remove inlet manifold,exhaust manifolds,and then remove heads to replace the valves
the manifolds should be the same for the 350and 305. be careful, however about the year of your manifold, older manifolds have the four center holes drilled at the same angle as the heads and the rest of the holes, newer manifolds have the four holes drilled straight up and down, and the two are not interchangeable
THAY ARE SCREEWED INTO THE SIDES OF THE CYLINDER HEADS WERE THE EXHAUST MANIFOLDS BOLT TO THE HEADS. THEY HAVE SHORT PLUG WIRES HOOKED TO THEM COMING FROM THE TOPS OF THE VALVE COVER.
Block and heads are the same. Manifolds are different.Block and heads are the same. Manifolds are different.
They are in the sides of the cylinder heads were the exhaust manifolds bolt on to the engine. They have black rubber plug wires hooked to them.
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.
In the cylinder heads. The larger valves are the intakes. You'll notice that the passageway leads to the exhaust ports where the manifolds or headers attach.
take out the cylinder head bolts
The intake portion of the 3100 starts where the throttle body (where the accelerator cable attaches) attaches to the plenum (upper intake), below the plenum is the lower intake. The exhaust manifolds are between where the Exhaust pipe connects to and attaches to the cylinder head. The first answer is great, but here's some more as I have just finished replacing the intake manifolds on my 1997 Pontiac GrandAm with the 3.1L engine. First of all, this is a two-piece manifold which is unusual, the first one I've see like this.... This engine is a 60 degree V configuration, and the lower intake manifold bolts directly onto both heads, essentially filling in the center of the "V", and providing air/fuel to the head intake ports. Its mostly obscured by the upper intake manifold that bolts directly to the lower portion. The upper and lower intake manifolds are cast aluminium. The exhaust manifolds are each on the outside of the "V", and bolt directly to the heads. They are cast iron (usually rusty iron color), and are covered by silver sheet-metal heat shields. There is a crossover pipe that connects them to a collector which connects to the rest of the exhaust system.
