408 Magnum stroker HEAD HELP!

I know I am a few days behind replying here . I am also building a 408 using a magnum block . I went with performance world bare castings (had the +.100 valves from a previous opps) And a set of speed master 1.5 shaft mount rockers and oil thru pushrods . The reason i went bare castings is i am running a solid roller . When you look at the flow numbers performance world is very close to trick flow. The speedmaster rockers have the oil holes for lubrication of the shaft . Cost on the bare castings was 1700 for the pair Canadian
