how to prt match heads to manifold
Don't "gasket match" which is relatively easy to do. Transferring the head port shape to the manifold for all cylinders is challenging. You might consider a professional, or don't do it at all. If the manifold opening is slightly smaller than the port opening in the head, that isn't all bad. The other way around is all BAD.
You may get different opinions.
Why the BBK, by the way?
