I've come across. They had a big "bowl hog" type cut done under
the valve job that really hurt the flow. IIRC, these flowed less than a
completely stock head with the OE valves and valve job.

Bowl hog? Is that like running a 70° stone as far as you can take it? If not porting, how should it be done when installing bigger valves?
