Gentlemen I've been sitting here agonizing over my chronic exhaust leaks and I think I see the problem, take a look at this picture, don't it look like the Hooker header ports don't match the location of the ports on the L31 Vortec cylinder head?

this is the passenger side head, can you see the black square outlines and how they are all shifted over to the right about 3/16ths of an inch, all four ports are like that, as if the header was bolted up a bit too much forward and not on center of the exhaust ports

am I crazy or do you see it?
