Exhaust Manifold

[maximo]

I have a 76 engine with the intake and exhaust manifold married. I want to get rid of that system and instead put an intake and exhaust mani that are separate. I already have the intake mani, but I'm having problems finding the right exhaust mani, cause the holes for the exhaust are square, the ones for the intake are round by the way. Can anybody tell me what year of 620 comes with the exhaust mani that has square ports.

So the down pipe, is this not something that my exhaust guy can take care of?

racnjasn? or someone has the flange avail.

the EX guy could make it from there.

Is that an actual header, or just a stock manifold?

[hang_510]

bagged_ is selling a stock manifold, which is as good, if not better, than a header for 90% of the builds.

 

the flange is to mate the stock mani to a custom 2-->1 down pipe.

You want this L18 or earlier L16 exhaust manifold.
