B210 Intake and exhaust options

[sick620]

My b210 is a 77 and has the style of intake manifold and exhaust manifold that are connected with a hole in the bottom of intake so fuel hits the top of exhaust manifold before flowing in the ports.. My intake manifold is cracked after trying to remove the pcv valve out of it finally got it (lol)... What years/cars have a intake manifold and exhaust that are not connected/have less smog stuff etc? I have read that a12 intakes will not work because of different port shapes is this true?

A12 intake ports are mostly round from what I've seen. What "A" motor is in your B210? Do you have round or oval intake ports?

1,200, B-210 and 210 all use the co-joined manifolds.

 

Cracked??? near the PCV valve? Just JB weld it. Clean with wire wheel, maybe dremel it slightly, degrease it and put it on.
