No unfortunately their not. I bought them second hand. Something happened to the guy's engine and he decided to go LS, but before he decided that he had his heads reworked and had the paperwork for it so I was sold.Quote:

You may want to go with a smaller retainer and you have to change the springs no matter what. I have the ultra pro for my 210 heads and I believe I am going to have clearance issues on the edge of the retainer that I did not plan for when I changed my springs. Now I may have to order a different set of springs for another set of retainers I have sitting here that would work

If you can get away with no girdles do. They are a PITA to run the valves and a pain to get to clear valve covers. I have come Moroso tall valve covers and I had to mill the webbing a bunch to make them work.
