Total "bill of material" for Aluminum head swap / Advice on where to save $ welcome...

Hope I'm not hijacking MRGTX's thread, but this may be info he can use as well. PWR & Mancini rockers are not far off in difference of price.
I have LA type head oiling, based on that, what are thoughts on:
PRW are Stainless with cup adjusters, needing ball pushrods. I assume requiring pressurized oil for PR/cup interface, either from lifter/PR direction OR reversed, coming FROM shaft, since the cup is inverted.
-VS-
Mancini-H/S are Aluminum with ball adjusters needing cup pushrods. I guess capture oil flying around inside valve cover since cup is upright.

One method over the other AND/OR one material over the other?
