I am going with ALL GMPP parts so I will not void any warrenty issues. I know aftermarket parts are cheaper, but dealers will give you crap for it when anything goes wrong.
just get a stock one from a member and have it (extra) honed and have your dealer install it, this is what I,m doing and it will be honed more than the gm honed manifold
