W5 heads

So Mullen cast the head too? (I said 'some portion') Also, back around 1992 I was paging thru some old pics at Koffel's and saw a big block head with unique ports and chamber which was designated with a "W" moniker...e.g.-Weslake. The engineering team at Mopar was one of, if not the first to develop flow bench testing and back then everyone was learning. Somewhere around 20 years ago some of the greatest head porters got away from using the flow bench.
Interesting, the 5 pics I have of the aborted B"W2" version has no visible markings or callouts, & I'm sure Mullin didn't cast them. It's unclear & not specified who actually designed them, but the text stated they "never made it past the flowbench", which is why I'd like to see a real functioning set tested(not likely ever). I think with just the ports raised & the correct valve sizes they were probably a lot better than given credit at the time.
