LS Engine OEM Coolant Block Off Steam Crossover Blocks

OEM GM Cylinder Head coolant port block offs. Good, clean condition with very little to no corrosion.

Each purchase receives one pair of used blocks.

Will fit any LS cylinder head coolant port including engines in many Chevrolet, GMC, Cadillac, and Pontiac models - 5.3, 5.7, 6.0, 6.2, LS1, LS2, LS3, LS6, LS7, LSx, LQ4, LQ9, etc

I have these on-hand and ship quickly. Typically 3-4 days to your door or less in the continental US.

I have other GM Cylinder Head steam ports available too. Check my other listings for many LS and swap parts.
