I would suggest maybe a hyd. roller setup like what most the other guys are running on prev. replies. That cam was more suitable for racing but mainly the rollers, if you chose to stick to that setup a rigorous maitenance schedule is needed. Every season I would check your valvetrain completely, generally they will need replacement if any wear is detected or excessive endplay.This involves removing the valvetrain for inspection, a nice Rimac springtester would be nice but they also have on the head springtester as well that can be found through NATIONAL DRAGSTER if the engine is non blown weak spring pressure or seat pressure is not as critical as they can be shimmed I don't see any reason why a couple a seasons on them is fine. If you are competing on any level all that goes out the window full maitenance prior to an event is strongly recommended! Frankly it is quite impressive to have that kind of mileage on that valvetrain with no replacement, hows the distributor drive gear? probably like a knife. If you like working on them stick with what you had but replace it all including the gear, send the cam out have it checked.
