push rod ?

Oh yeah I forgot to mention that. The oil coming up these hollow pushrods would be additional to that which is being pumped through the normal LA oil circuit which goes to the hollow rocker shafts,and into the rocker arms through their bearing surfaces.
That geometry was the price to pay for the high mounted camshaft which makes fitting a stroker crank almost a breeze. Yay on the room, Boo on the geometry.
If you dont have the hold down straps, either figure out a fool-proof way to keep that baffle down, or pitch it. It will run fine without it. No worries.
