Stock Mopar Rocker Assembly... Sheeesh!

Out of alignment?!? Not sure how that can happen unless they were assembled incorrectly (They are handed left and right). Or totally worn out.

Anything more than the heavy duty OEM style and new shafts would be a waste of cash on your setup. Roller rockers are really hyped up, but generally the increase in performance is due to a massive lightening in the drivers wallet and not reduced friction.

Roller rockers are seldom much lighter, but move weight out over the valve tip, exactly where it is most detrimental.

Increased ratio will increase lift for a given duration, but also increases load as seen at the cam, lifter and pushrod. This increase is exponential as RPM rises. Make sure your springs can handle it.

Stiffer springs use more power, and put a higher load on everything, make sure your timing chain can handle it.

Better bet would be to reduce mass of valvetrain components. That way you could run a lighter spring, and the stock rockers would flex a lot less. But within the RPM range of that cam, stock parts will be your best bet.

Fully rolerized rockers use a caged needle bearing on the shaft. If one of these lets go, all those little needle bearings are loose in the engine and will head straight for the oil pump. Stamped or bushed rockers make less shrapnel, and fail less often.

Roller rockers sure look cool, but they are real hard to see with the valve covers on.

Double check your carb CFM, I bet it's a 625. If you are running a 500, a carb swap will gain you more than any high-zoot rocker setup.
