What exhaust manifolds and flapper or u going with? Just curious because iam doing same thing.
Undecided on this one. GLM conversion kit is $625, but some have had issues with the mating surfaces of the manifold/riser.. I could easily fix this myself, so not really a big deal for me. But can also get the Barr conversion kit for $800, and everything "should" be slightly better quality, without the mating surface issues.
As for flappers, and all gaskets, those will be OEM
