Perhaps you shouldn't take his statement as an absolute.

Common sense?

As stated in a prior post, legally, Super Stock cylinder heads can be welded and/or epoxied. The angle milling does not have nothing to do with the volume of the ports. The majority of the Super Stock Chevy small block cylinder heads ports have been reshaped with epoxy and most are configured to an oval port from the OEM rectangular port shape.

Therefore, any Super Stock cylinder head can be returned to the appropriate port volume by welding or the use of epoxy.
