The Clifford double valve springs worked perfectly and are now installed in my head. I looked all over there website and it appears that the don't make them any more. Glad I had some NOS ones in my shop! We also used their hardened valve locks and retainer.
IIRC they are 130 on the seat and 260 at lift.
I'd have to say since mine is one of the pre-production heads and was made in Australia that it wasn't machined the same as the later US made heads. Thanks guys for all your help trying to find springs for it!!
Later,
Doug
