What is the correct procedure to replace the intake manafold and heads on a ZZ4 Chevy 350?
Same as a standard small block , just do every thing carefully
and use good intake manifold gaskets or you,ll get a vacuum leak.
Just follow a manual carefully, it's not hard to do ,make sure
everythings clean and done correctly. Invest in A Chilton, or
haynes manual which you can pic-up at any parts store) auto zone,
O'rilleys, ect) Then it will be a snap. Basicly you will take off
your carb & Distributor when changing your Intake mannifold.
The heads well I havent done those yet but I dont think much eles
has to be removed now you may want to take some other parts off but
that would be just to make life easier. For example I had to jack
my engine up when replacing the oil pan and I removed the fuel pump
to make it easier on myself. Granted I had to replace the fuel pump
gaskets but it was worth it to me.
