I was told it was a splash shield for the lifter valley
If it is I can't figure how it attaches

Best if used on a factory-type manifold (iron, LD340, Stealth, etc.) where the bottom of the plenum is directly exposed to the valley. If you're running an Air Gap/Victor type manifold, it's unnecessary.
True. I should have been more explicit and said "It's use as a splash shield becomes unnecessary".As John pointed out, it's best feature is lifter retention so even with an Air Gap and perhaps even more so because a free breathing engine is more likely to have a valvetrain failure..
Had this happen the one time a crane gold rocker loosened. That valley baffle saved my fresh rebuild. The rocker wasn't so luckyThe best part about it in my opinion is that if the Valve
Train comes apart = It retains the lifter in the bore and keeps
the oil pressure from going to Zero.
The later blocks and many R block have bosses in bottom of
the lifter bore which I like better to secure the tray.
Pay attention to pushrod clearance to tray as often it is too close.
