mydooris4 Posted 5 hours ago Share Posted 5 hours ago Hi, I'm trying to swap my rb20 head to rb26 camshafts. I noticed the hydraulic lifters have an oil hole on top for the cam lobe but solid lifters do not have the hole. Do rb26s have a different cam oiling design than the hydraulic rb20? Similar to how the L-series can have a drilled cam or an oil spraybar? Also are valve springs different from factory between hydraulic and solid lifter rb25s? Thank you Quote Link to comment Share on other sites More sharing options...
