96-2000 454 exhaust manifolds...fitment?
I like the looks of the 96-2000 454 exhaust manifolds more that the stock ones on my 78 GMC...just wondering if anyone on the board has used them and if there are any fitment issues I need to be aware of. Thanks

They look like they won't be an issue, the flange thickness where it bolts to the head looks a little thin compared to the old school manifolds. I just dropped a 454 in my 78 K20 and used the 1970 Chevelle 454 SS factory manifolds and they fit perfectly with room to spare.
