Thank you keep in mind my model heads are simply 1975 smoger castings that were ported at Mullen and company !!!!
They are 5 years after the TA heads were campaigned and 1 year before the W2 was revealed my castings are mentioned as
(W1) in several 1975 publications.
Mullen offered a heavily modified (360 casting - same as mine but special welding needed etc for Pro-Stock class I wish I had some of those and my numbers would be more impressive nevertheless for class I want to race in these will work until I desire something else. I have a alot of money in these and many will question my direction versus other routes but These heads are Super rare to me and im honored to have um .
