Message -Fully machined the block porting the water passages near #5 and #6 cylinders.

-Bore pistons and hone w/torque plate.

-O-ring block and use copper head gaskets

-ARP main stud kit

-Arias or JE forged pistons, probably 2mm or 3mm overbore w/NA oil squirters and Swain coating of top and skirts

-New Eagle rods

-Polish crank

-Moly rings

-JWT cams if going w/JWT turbos. Or Jun cams.

-new Valve springs to handle the higher lift cams

-check the lifters. If in specs, re-use them

-port match upper and lower plenums w/heads as well as exhaust manifolds w/heads. May want to wait for Dupree header-like manifolds (still in development).

-Stainless steel valves (especially change the exhaust ones) and Swain coat them.

I'd rather do all this, than a new short block. Just gotta find a shop that has experience w/VG30s.
