I pulled the valve covers off the 440 in my GTX to see how things looked (car has been sitting for years..).

Looking at the rocker arms- and how the meet the valve stems- does not look right on some of the cylinders. They are not mixed up (left vs. right). The small hardened spacers are between them. How are they to remain centered on the valve stem tip?

In pic 1 below, of cylinder 1, we can see that the exhaust valve rocker is far to the right of the valve stem center:

In Pic 2 below, of cylinder 2, they are centered and have much less endplay. Also, the rockers in pic 2 look to be of a different stamping:


Are the rockers in pic 2 OEM Mopar pieces and the ones in pic 1 generic replacements? Any suggestions on all of this is appreciated.

Looks to me as if someone didn't know that there is a right and left offset to the rockers. Put the right offset in your right hand and the left in your left and that is how they are installed as you stand beside looking at the engine.

In the first pic it looks like somebody was hammering on the rocker on the right.Get new ones.

Looks like 2 different batches of rocker arms to me.

Is it my imagination or is that a small block rocker arm in the first picture??

You have the wrong rocker arm on it. Like someone mentioned, it looks like it's for a small block, but it is the correct "left"....just for the wrong engine.

looks like the spacers are a bit skinny too, but it's been almost 20 years since I had a BB under my hood.

The spacer is fine , that is the normal big block stamped spacer . Don't have a picture to compare to but I think as mentioned that is a small block rocker .

Thanks everyone for your input!

Look at the top right of the rocker.Its all hogged out.Thats why its sitting so far forward and off to the side.New rockers are in order.Heavy springs and or a big cam will do that fast.Rocky

Thanks Rocky! Looks to be the case.
