Hughes retro hydraulic roller lifters

you can tighten the compcams hyd. rollers down 3/4 turns, and it will help. I ended up going solid roller on my 406, and it was quieter than the hyd. !
Mine tics after its warm and shut off. I'm gonna cut the top out of a shitty chrome valve cover and check it that way while it's running. It's a new engine. 416
