I am looking into doing a full 3L swap or a hybrid.

My main consern is final HP numbers and reliabilty.
My coworkers dad is an expert mechanic that mantains a 800 HP Sanoma Drag truck but i am just not sure if i should go full 3L route or do a hybrid. Also, if i do go full 3.0L and i buy new heads to bump the stock compression ratio, is that pretty much doing the same thing as using stock 2.5L heads and PnP'ing them?
