BHP billet rocker clearance

[stargazer7467]

Does anyone know if the Brad Hill rockers will have clearance with a hemi head milled .065? Wanting to pull the trigger on a set and havent saw much feedback on them.

You should hit up Brad directly ... The valve cover needs the baffle removed and minor clearanceing . if you are running larger than a .275 lift cam the spring pockets need to be cut and widened for heavy springs . but I am not sure what the valve clearance is with milling . Barry young has done a lot of work with these heads as well as ole4 and others sure someone will have answers for you

i just did, i forgot he was on FB. Im running the black mamba 275 lift 246 duration cam. he says i may have to make releifs in teh piston.

Or you can run the dished piston... I know it somewhat defeats the purpose of milling the head... But just another,option...
