Rocker Arms
So, my uncle said something about tightening up the rocker arms to do something so it'll do something else...
My question is... How tight to you tighten each one? Is there a certain pattern you have to tighten them up in? Why would tightening them up help?
I've got a 300 I6...
Thanks guys!
EDIT:: Also, A few people have been saying change the rocker arms to Chevy Rocker Arms...
What year, model, etc. etc. for the rocker arms?

The rockers nuts should be torqued to 17-23 lb/ft. Torquing keep the right amount of tension on the rockers so that they don't loosen, and the valve springs and puch rods operate without any slack. They all operate independently, so the particular order isn't critical. Some of the later 4.9s bolts instead of nuts and use fulcrum guides, but the torque specs and procedures are the same.
As far as your last question, I'm not sure why anyone would recommend putting parts from an inferior truck into your Ford....

THAT'S WHAT I TOLD THEM!!!!
EDIT:: So, how exactly would I go and do this? Just go and torque down each one between 17-23 lb/ft???

I believe your uncle thinks your valve train is adjustable like a Chevy. It's not. If you tighten the rockers, you are really doing nothing but making sure they haven't come loose, which they probably haven't.
I am not sure, but I am guessing the chevy rockers may have a different ratio, so they would give you more valve lift without changing the cam. But I would imagine there will be some other modifications to make this all work.

The Chevy truck is absolutely inferior, however, the Chevy rocker arms do have more lift than the stock Ford rocker arms. I'm not exactly positive how much more, but I do know that it is in fact more.

If everything else is stock, I don't think there'd be a noticeable difference. I think that changing to Ch**y rocker arms would be one of the thinks you'd do to squeeze that last couple of horsepower/torque out of the engine. But if I were to upgrade my rocker arms, I'd spend a little more money and get something with a little more lift than the Chevy rocker arms. Plus, it'd be a disgrace to have Chevy parts in my engine.
