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

The 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.
 
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.

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..

True. I should have been more explicit and said "It's use as a splash shield becomes unnecessary".

Had this happen the one time a crane gold rocker loosened. That valley baffle saved my fresh rebuild. The rocker wasn't so lucky
