Roller Rocker Arm Situation

[Ronno6]

Tall valve covers wouldn't solve your valve cover issue? I know it does nothing for your side to side issue but, at least rockers wouldn't hit your covers. They're pretty cheap. I've got a set on mine.

Yup I have tall valve covers.
The issue is not how tall the arms/polylocks are;
the issue is the very edge at the pushrod end is contacting the vertical wall of the valve cover.
Basically stated, the end of the rocker arms may scrape the inside wall of the valve cover as they move up and down.......

got any pics of way the roller looks like on the top of the valve stem. that’s what matters.

Here ya go....I am not the best photog in the world tho.

Thanks, Kenn.
I was hoping to stay with a full roller rocker.
Got a great deal on these:

They are self aligning, but I'll use my adjustable guide plates as well.

Are they centerbolt covers? Perimeter bolt covers should have more clearance.

Some models of Scorpion rockers are narrower than others............

Mine were the blue ones just like yours

 

[Ronno6]

Looks like the Scorpions are going back.
Gonna see how the PRW's and the adjustable guide plates work out..........

With the self-aligning rockers, ditch the guideplates altogether. Besides being redundant, the angle those heads put on the rockers can cause binding when using the plates.

why?

No, rocker adjustment process will be the same. The overall height of the studs will be lower, that's all.

I'm fearing that the extra length of the stud will either bottom out on the blind holes or protrude into the intake runners on the others..........
