Need an L20b exhaust manifold- square port (headers maybe)

[hessianben]

The exhaust mani from my L16 is too short and too close to work on the L20b with square port head.

Looking for a non-smog square port exhaust manifold in southern california,

will consider square port headers if they fit.

Will drive to pick up.

Thanks guys!

i need that flange that bolts onto the mani in the picture so i can get my exhaust done!!:)

i have an l20b smog mani i dont think the l20b has a non smog manifold looks to me the issue isnt the manifold itself but the colector that bolts to it i would make it a single pipe as soon as possible then run one pipe so that way it clears or you could just go to topend performance and get the header

The only smog thing about the exhaust is the bung for the EGR tube which is easily plugged with a metric pipe plug.

 

The '74 610 was the only L20B that had a square port exhaust manifold with 4 into 2 just like the L16/18s
