If he's gonna go with new pistons, just get them flycut, and then mill the 799's to bump compression. No PTV issues, and would end up making just as much power. Use the money for better rods. Imo Mast heads are $1k BARE, plus you need the offset rocker arms to run them.
Spend the money on good forged pistons and rods. Flycut the pistons if you worry about ptv because of cam, mill the 799's to bump compression, use the extra cash to get them ported if your concerned about flow. You'll come out cheaper then the heads alone.

Theastronaut- I wanna see some pics of the homemade IR setup on here (I'm on ls1tech but way too lazy to go through all their threads)
