How-To SR20 Dual Rocker Guides

Made this video about two years ago and forgot about it. Just wanted to help explain how to do the dual rocker arm guides on sr20de or det engines. Sr20's frequently throw rocker arms at high rpm or when hitting the rev limiter. Rocker Arm Stoppers "RAS" came out claiming to fix this issue, when in all reality they make matters worse. Instead of throwing the rocker, the RAS forces the rocker to stay in place, which cause the rocker arm to simply shatter 99% of the time. The Dual Rocker Guide mod has been around for a long time but has never been very well known. This is a proven method to eliminate the rocker arm from popping off at high rpm/rev limiter. The factory flat shims have minute differences in thickness, but the guide shims are all the same exact thickness. The hydraulic lifter will take care of any negligible difference in the guide thickness with no need to re do or "check" the valve lash. This is a very cheap mod as the guides can be found cheap at most junkyards from any sr20 powered nissan... I never did do the video about setting sr20 base timing, maybe some day I will have another chance to do so, apologies.
