The Plymouth Weslake DOHC Motor from the 60's
This thread is a MUST read on Bob Mullen and mid 70’s small block heads.
mid 70's NOS Mullen small block race heads
An old Mullen employee even chimes in with all kinds of cool details. Lots of pictures and comments from back in the day.

“I picked these up in a package deal. Part number on box is7007194. Part number on head is 3769974. I have a matching pair. I really don't know their history or viability of use (any good to use?) so I thought I'd ask. What were these originally for? They are fully ported/polished and marked Mullen. They have "360" cast into he head as well. I even have the original boxes which I think are cool. The only think I find odd is the intake bolt pattern is slightly changed . It can be reversed easily, but why do that in the first place? Anyone familiar with these? I'll try to post some pics. Thanks in advance”
