I Know this is a wild shot,but I'll ask.I have a set of 7m5 Heads from a 72 455.I'm in the process of finishing my 455 build and I was wondering if i could use those heads.Now the heads already have a valve job,cut .060 on the deck,.030 on the intake,7/16 screw in studs and gasket matched.Now i'm guessing i need around 9:1 for my cam(244/252).Now from what i understand the cc's of these heads are way to high for my app.But seeing how i'd like to get this done,and like most don't have $800 for a good set i figured i'd look into this route.btw my block is punched .060.thanks for any info.
