Selling a pair of ported LS6 heads with the genuine lightweight sodium filled valves and low mileage BTR dual springs. Bought these on here for a friend but he's going in a different direction with his build.

These are used, and could use a good cleaning and flat mill as usual with used heads, but other than that they are in perfect condition. Mileage on these is unknown, but the springs and valvetrain have about 5,000 miles on them. Asking $1000 and I will cover up to $50 of shipping due to a deal I have at my work, the difference is up to the buyer if there is any.
