Oh I wish I had this knowledge 13-14 years ago when I first ran the Edelbrock Victor cylinder heads.Start researching Mopar rocker geometry. Lash caps may keep the rocker from contacting the retainer, but will make the true geometry worse, and that is the root of the problem here. From the damage I see, you are lucky you haven't dropped a valve yet. The thing about luck is, it always runs out. Take care of the geometry, and avoid a major failure.

Ouch!unfortunately when i got the motor from the builder the first time it dropped 3 valves and busted 3 pistons
I have been using these same heads without those issues. My install height is the same, but I used Harland Sharp rocker system in a 1.6/1.5 combo. 4 seasons now mostly street, but some track. Goes thru traps at 7100.hi maybe some one here is having the same problems i have this is the second time having valve stem keeper problems and retainers hitting the rockers
What's not perfect about it?
You dirty dog! My 500/440 made 848 HP @ 7,200 rpm way back when with the same rockers and the same lousy geometry. Still have all the same heads and short block. I wonder sometimes about putting it all back together and trying with the valve train correct this time.What's not perfect about it?
Unfortunately, for being a "race" head, the shaft stands were not put in a reasonably close location to have good geometry, and no amount of fussing with the spring and retainer combination will change that.

Maybe the OP can fill us in on whether the valve tips are actually below the top of the retainer/locks. It doesn't look like it to me, but the angles may be giving a different perspective.Relocating the rocker shafts would not have solved the issue on the OP’s heads(using the parts they were assembled with) with the sides of the rocker, at the roller, contacting the retainer adjacent to the locks.
