If you want to turn serious rpms, you have to get away from that hydraulic camshaft. With this adjustable valve train kit, you replace the hydraulic lifters with our adjusters and mouse springs to keep the follower in place at high rpm.
Adjuster kit includes eight lifter adjusters and threaded inserts. Mouse springs sold separately, but required.
Machining Required: You must machine .200" off the lifter boss on your stock heads.
