Cylinder heads are installed on a Chevy 454 big block engine by placing the gasket down on the engine block and positioning the heads over the marking tabs. The bolts are then installed and torqued to specs in sequence.
This question needs to be clarified. What block and heads do you want to install? Chevy, Pontiac, Olds....which one?
ANY year that has a carburetor intake manifold available to install on the block/heads.
Best place is in one of the cylinder heads, by the spark plugs. Or, the intake manifold, near the thermostat housing.
they came with "186" casting number heads.........
Yes they are the same heads.
There are many places where one could purchase small block Chevy heads. Some of the best places to purchase small block Chevy heads at places like Amazon or Auto Zone.
Yes, and well.
NO.
Yes they will, but 305 heads have a smaller combustion chamber so it may raise your compression ratio.
These should be double hump heads. They are very sought after heads.
