So I'm working on my 383 and just about to put the rockers on and set them up for fire-up. Then I remember the guy I bought the engine and project from put in 7/16 studs to replace the 3/8 that came on the AFR's.

The burning question, what method of guide plate adjustment do I use to assure the 1pc plates are aligned, or is this something that goes together as well as possible and we just live with it as best we can?

Thanks for any help, It's been a looooong time since I did this part.

I am unaware of any alignment issues with guide plates.

It's all about them going in... and that's about that.

That's what I've finally concluded. Obviously, a one piece plate cannot be adjusted from slot to slot, but I guess I just psyched myself out by over-thinking a fairly simple part. Thanks for the response.

I hate it when that happens...

keep us posted on your progress!

It depends which heads your using..With my Dart pro 1 heads it was a bitch getting the rockers set up because of the way the larger valves are set in the head...I have heard some AFR heads have this same problem...With my Dart heads you have to push the guide plates on cylinders 3,4,5,6, as far to the side as possible to get the roller tips to almost cover the valve tips..I was upset by this until I called Dart and talked to their tech guy..He told me the roller only has to cover 70% of the valve tip to function properly..He said if it bothered me I could buy offset rockers or use split guide plates for those cylinders to fix the problem...On stock heads and most aftermarket heads the rocker sits straight up and down on the head. On my Dart heads the rockers sit at an angle on those 4 cylinders and the guide plates and pushrods have to be pushed over until the pushrods all but touch the side of the push rod slot in the head, and even with doing this,the roller still doesn't cover the whole valve tip...WW....
