At least that is the newer castings with the extra material above the intake ports. I ended up using PAC 1326 valve springs with thinner valve spring locators (I think 0.030") that PAC milled for us, plus the +0.100" PAC Ti retainers, standard locks, and lash caps. Using the max wedge rocker shaft blocks we just set the shaft height where it looked OK, but it would have been nice to have the offset like shown here.

I have some photos, but need to figure how to post them?
