Not running yet but I used Hughes 1.5:1 rockers and custom Smith Bros. Pushrods. I don't recall the length. Lunati VooDoo Hydro Advertised Duration (Int/Exh): 268/276; Duration @ .050 (Int/Exh): 226/234; Gross Valve Lift (Int/Exh): .494/.513; LSA/ICL: 110/106. Heads were ported and set up by MRL so these were purchased as bare heads.

The Comp Magnum (not Ultra Pro) rockers I had didn't line up well geometry wipe wise, a kit from B3 fixed that but the tunnels got in the way even after opening them. The Hughes fell right in with a small shim, but that was these heads.
