Summit Racing™ Coolant Crossover Delete Kit for GM LS
This new Coolant Crossover Delete Kit converts the GM LS factory four-corner coolant crossover system to a two-corner system by blocking off the steam ports in the rear of the cylinder heads.

That creates more clearance for intake manifolds, eliminates unnecessary plumbing and adds more firewall clearance for engine swaps in tight engine compartments. The kit includes two billet aluminium block-off plugs, sealing O-rings, and bolts and does not require the removal of the cylinder heads to install.
