5.9 Magnum Torque motor build?

Thanks you wyrm.. I am intrigued by the lighter valve train parts you mentioned. I was thinking about my 1.9L Opel engines the other day, cam in head, with the stock hydraulic valve gear that would rev past 8K over and over, all day long with nary a wimper and just some single HiPo valve springs... no fooling. Factory stamped rockers on studs; think I broke 1 rocker in 6-7k miles of racing, never broke a stud. Gotta figure out someday why just adding a pushrod changes things so much for the worse. Of course, the valves are a lot smaller; I need to weigh some vs some stock 318 valves for example.
