The heads will need to come off.
I am hoping to run the current grind.
The Comp hydraulic rollers shot craps - clatter on startup and bleed off very quickly, will barely pump up when hot, less than 500 miles and they are junk. They have .800 rollers
And this ^^^^^^^^ is exactly why I won't do a hydraulic roller any more. To get the spring loads high enough to deal with the faster lobes they hydraulics won't take it. I used to run 160-180 on the seat and they hydraulics didn't like it.
When I started using hydraulic roller lobes and solid lifters I could up the seat pressure to 220, the lash doesn't move, the lifters and springs live just as good or better than they do with hydraulic lifters.
