The Plymouth Weslake DOHC Motor from the 60's

A common misspell...sorry!
The W2 head came after my dad departed from KBRE in mid 1972 if I recall. The D5 head was a twin plug Hemi head that Chrysler had trouble with the guides so Tom Hoover of Chrysler had dad and Bob Tarozzi made them work. I just saw a set pop up on Ebay for 4000.00 USD. Thanks for posting the photo of my dad and Hutch!
