I don't have a lot of experience with crossing over the intakes, I know the biggest differences is the fastening holes. 8 bolts for vortec , 12 bolts for first gen Chevy heads and the vortec bolts are on a different angle. They do make a jig to drill the manifold or one for the heads to fit, but I still think there is still leaking and fitment issues.
