We are finishing up a 489" LS6. No stone was left unturned on this project. The cylinder heads received hardened exhaust seats bronze guides and positive valve stem seals. That was paired with a fully rollerized valvetrain including steel rockers. The rotating assembly consists of a forged 4.250 stroke crankshaft, s**t forged rods and SRP forged pistons. The factory GM snowflake intake was ported and then v***r blasted and satin cleared it for a nice mostly stock appearance.
