These are not like the other brand rockers. One thread showing was the best for the MP rocker. Not so for Hughes on my engine. Their instructions clearly state to start out with the adjuster 0.450" below the rocker with LA blocks as a starting point. No magic number of threads showing. The detailed instructions are on their website. I've followed them to the best of my mechanical ability. A new set of hands and eyes and experience would be helpful. This is a new experience and user error is probable. In a rare case my heads may be the problem. I have no idea what was done to them prior other than some porting.
This has been frustrating with conflicting information and my inexperience as well. Hughes checked my rocker and it's fine. Today, they still say I should get the .544. **** if I'll get .544. I'll waste another couple hours on it tomorrow. :cwm21::cwm21:
