I bought these heads brand new 2 months ago from GN1 and decided to go a different direction. These heads are for a 1986 or 1987 Buick Grand National, T Type, Turbo T, or GNX 3.8 liter turbo V6. The heads feature a 170 stainless valves and exhaust valves are stainless 160. They have new keepers, EGR filled for delete, new retainers, and new springs for a roller or regular hydraulic cam. They also include the roller valve spring upgrade kit. Brand new, I took one head out of the box to take pictures and the other head is still sealed in the box it came in. I paid $2800 for them, will sell for $2350.
