Tonight I installed new Hughes adjustable SS roller rockers to quieten down some top side ticking. Unfortunately the sound is still there. The ticking is mainly on the left bank and sounds the same as when I had the stock rockers and push rods. Anyone who wants to go through the preload procedure please go ahead. I'd like to see if my method was good. With the zero preload and then 2.5 turns to preload it I thought there were only about 3-4 threads actually engaged. This is a 5.9 Magnum. Could it be that there is going to be a certain amount of ticking I have to get accustomed too?

It's not a broken flexplate is it?
I had one that sounded just like a lifter/valvetrain tick and it had a small crack in the flexplate.

The cam is a roller cam from Hughes. Heads are RHS. Pistons are KB at .03 over and .017 above block deck. Edelbrock intake with an AFB. The flexplate came from a 2002 Ram so I could hook the Magnum to the 904.

Which brand hydraulic roller lifters are you using
He didn't mention the Roller lifter....only the Roller Rockers
and from the brief installation of the Harland Roller rockers that I have used (for a week now) 2.5 turns is way too much. I was told to use 1/2 a turn after the pushrod stops turning in your hand
You sure you don't have a collapsed lifter? I still have one but the car is gonna sit for a while until I figure out if I am going to remove the intake and rebuild the lifter AGAIN. Or buy another lifter and put it in its place.
Since he said he had a roller cam, I bet he has roller lifters.

Rhoads brand lifters make a ticking sound. Maybe some others do also.

If that were the case I'd live with it. However, right now I don't know if I have to live with it.
I was told by Hughes that the lifter I bought from them likes a lot (.08") of preload, hence 2 to 2.5 turns. I did not use the putty on the pistons, which in hindsight would have been a good idea. According to the setup with the RHS heads and pistons there was no concern about interference but then anything is possible.
