The lower intake won't. The rest will as long as you buy the vortec specific lower. If your rebuilding your engine an want to run this you would probably come out cheaper to buy heads to fit the lower rather than rework your current heads an buy the special lower. Just my opinion though.
Again, only if you buy the specific lower vortec intake. No stock tpi lower will fit a vortec head. They do make an aftermarket lower that is vortec compatible, it's around $400....
