rocker arm torque?

[BlakeOfDoom]

I'm wondering if the issue I'm having could be related to the rocker arm bolts being too tight. I'm getting a slight intake backfire when I let off the accelerator and The engine is running a bit rough in park. When I put the truck in gear it will start chugging away and feels like there is no power. I ran a compression test and everything is around 150psi. Would this issue come from having the valves too tight?

The rocker arms are an "assembly". There are 3 bolts per side. You tighten them down tight to the pedistal(sp?). I don't remember the torque #, but its pretty tight.. being too tight won't make the valve not close, it would just break the bolts.

Here is a pic of the bottom of them.. you can see how it is just an "assembly".

Changed my mind

I'm not sure if its the assembly, I did follow proper torque for them, I wasn't sure if it made a difference at all in valve lash.

My compression was good so I'm leaning away from the valves. I'm not sure what tests to check, the idle in park is starting to smooth out but when the truck is in gear it just chugs away. the acceleration is not smooth at all. the rpm dips below 900 when its put in gear, and gets really loud. new plugs, wires, cleaned maf, nothing seems to be helping

Blake,

How did you resolve this? I had a similar issue and backed off the pedistal torque to increase valve lash and that made the engine run better (stopped backfires through the intake). However it's still not quite right.

I'm curious if you found a setup that worked?

Thanks
