Put the guide plates back in. Taking them out screws up the geometry. You can remove them but need to either shime the mount or different push rods to make up the difference in height(thickness of guide plate). Get the GP back in,chase/clean out the threads, torque them down to 25 ft-lbs with alittle blue loctite. 21lbs(oem spec) doesnt seem to work well with some motors as it gives a loud valvetrain(ticking).
edit....follow the firing order starting with #1tdc then turn the crank every 90deg and torque down the corresponding rockers

okkay.. so i read a couple of other threads about these roller rockers and this one seemed to stay on topic even after 3 pages.. so. do you have to turn the motor over to tdc for every cylindor or just bolt on and ride then re check every now and then... ive seen so many diff opinions. what is the easiest and fastest way? (know it aintgo be no thiryt minutes lol) ..
Don't know about the Ram's but on my Dakota RT there's a gray connector at the back edge of the battery tray with a single brown wire going to the starter. Disconnect the connector, clip one lead to the end going to the starter and the other end to the positive post of the battery. Pushing the button will allow you to very slowly rotate the engine to bring the intake and exhaust rockers to a level position for proper torquing. It actually took me longer to take off and put back on the valve covers than it did to install and torque down the RR's!
Before I installed my HS 1.7 RR's several years back, I did a baseline dyno run on a completely stock engine. After the install, I went back for another dyno run and it showed an increase of 10hp/10tq. Not bad for a very simple bolt on mod. Even the guy operating the dyno was very impressed with the increase!

The stock manifolds are actually not too bad. You could go either way. Headers help a little but not all that much. The biggest gains I got in my exhaust was when I went from a stock cat with 2.5" output to a 3" Magnaflow cat and catback. Now that was answeet upgrade. However, if yours is one of the years that has the y pipe from the factory then get rid of that too while you are at it as that is supposed to be really bad. My year didn't have that though s I never had the pleasure of seeing how bad for myself.

Thanks. Can you link me to someone's setup where they used adjustables, assuming aftermarket heads/cam? lol I feel you've got a much better search method given the threads you've come across on here. Feel free to PM to me if its a clutter on this thread.
Much appreciated.
MOPAC? link to the rockers? You didn't want to go this route?
