i want to know if anyone on h-t has performed any cryogenic treatments on their valvetrain such as titanium retainers, rocker arms. spring seats, etc. im curious if anyones had any success on the wear resistance and toughness it has to offer...this proccess in my opinion would be effective for our chilled cast camshafts along with rocker arms...does anyone else have any input im curious to know what you guys think??
