How many times you going to quote me?, I'm starting to feel like a 318 head celebrity man!. When I built that engine I had the ability to port heads, I had access to a flow bench, I had the freshly machined parts sitting there at less than half the cost since it was bought second hand with very low miles. AND this is the big one, there were no good low buck heads period. Pro comps were junk and not all that cheap considering and edlebrocks, well edlebrocks always been proud of their heads. With todays cost of machine work, parts and time/labor to port heads it makes no sense to me to do it again. Especially when there is a ceiling on performance that cannot be overcome with a 318 style head. I see their build as an experiment plain and simple, interesting?, yes, practical?, no.
