Are you looking for the traditional cast type valve cover, or will a race style sheetmetal valve cover suit your needs as well.
CNC-Dude how is that project comoing?
There is also another cast aluminum valve cover out there from Precision Machine that pops up on E-bay every once in awhile.It will fit either a Ford or a Chevy by using a adapter flange.Think ithey go for about the same price as the Clifford one.
