Default Exhaust manifold

Right side is cracked 2-3" above the heat riser, 79 stock 350 with a/c. Was wondering if anybody has tried the Dorman replacement manifolds or have a good one for sale? Ed

Ed, I have a set of mint original ones off of my '77. These are off a California car with the air tubes in them. Your car may not of had the air pump on it.

Zips sells a set of plugs that screw into the exhaust manifolds to plug the air holes if you want to do that. Just steel plugs to block them off. Not expensive either.

And I have a perfect heat-riser if your going to replace yours. This one has a lever and a ball on the end to lift the exhaust valve once the car is heated up. but it's only good for if your going to bring the car up in the emissions standard.

Thanks Binnie but mine doesn't have the air tubes or pump so I'll pass. Ed

I've got a pair off a 78 L48, no smog holes.
Both sides are actually the same, no. 3932461 RH 17 GM
One has a slightly hogged out hole for one of the 3 flange studs so might just toss that one, other one in excellent condition but you will need to add the 3 studs for the exhaust pipe flange.
$20 + shipping.
I'll even sandblast it
pics if you want.
