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? ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500

The flexplate came from a 2002 Ram so I could hook the Magnum to the 904. ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500

How is the best way to find it if there is a gasket leak? The head gasket is .052 thick and all the valve train came new from Hughes. Unless I did not understand I took the nut down on the rocker until the push rod would spin but with resistance (0 pre-load) and then turned it 2.5 times and locked it. ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500

I bet you have damage... A exhaust leak can be found with a 1/4" id plastic tube held up to your ear and the motor, it works good. Last edited by Challenger 1; 05/02/12 09:56 AM.

I am no engine builder...but when you put it together, did you put play-doh on the piston, crank down your valve train and adjust the "2.5 turns", rotate your assembly a few times and make sure your valve wasn't slapping the piston (or making an indentation in the playdoh) I was worried the larger valves were going to smack my pistons because I have flat tops. I used the above method and made sure I was in the clear. Family owned 1969 Charger R/T DualQuad 440/727/GVO/3.55s

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. ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500

I did the typical Chebby 1/2-3/4 and they were really noisy. Then went to 1 1/2 and they were a little better. Even after adjusting 2-2 1/4 the engine still has a good bit of noise from the top end. (Not so much a lifter tick) but there is noise. I'm also running Hughes cam and hughes roller rockers.

Which rockers are you using? The reason I'm asking is on most adjsutable rocker arms the adjusters are 3/8 diameter with 24 threads per inch, which means one full turn is .042 at the lifter, the rocker arm ratio multiplys so I normally try 1/4 to 1/2 turn preload and then drive it some so the lifters get a chance to pump back up from adjusting them. If you have the stock late model rockers like SB Fords and Chevy disregard my procedure Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

The rockers are the 350 GM rockers. The rods Hughes sent me are longer than the factory ones. ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500
