Help identifying rocker arms...

I'm sure it'll thank you in performance once you find and fix them all.
We've all seen it before... they threw money at it but it didn't work. It's a 360 with Eddy heads, has an air gap and a 770 holley... msd 6a & distributer, some sort of aftermarket cam (probably a comp if that's what the rockers are). It's .020 with perfect looking holes still... but the pistons are way shy of the deck and I see the mechanical advance is stuck...
It'll be in the machine shop next week for a few things... want it 10.5 to 1 with a voodoo in it... make sure the rest is tuned right.
That should wake up my slant 6 Dart :)
