in my opinion

your motor is going to blow up in your face.
cast pistons?
your pistons coming out of the hole is scarey.
.005 out of the hole
plus .003 bearing clearance
plus .007 piston rock
=.015 out of the hole
with a stock .043 gasket
your going to be .025 too close on piston to head clearance
your cast piston is going to whack into the head

porting oil channels with a solid roller is counter productive
your going to have to install oil restrictors or you going to suck your oil pan dry
