What is the difference between the mounting patterns for a manifold between the Vtec and non-Vtec heads? I'm looking at a manifold and was wondering it a non-vtec one can be redrilled to fit on the vtec head or is there more of a mismatch than that?

 

Disregard my last post. I found a manifold from Extrudabody that will allow me to bolt the webers to the B18 head. One more problem solved!
