NEW FOR 2024!
*As of 12-18-24 the polished finish is out of stock. We have plain cast and black available.
***THESE HAVE A SPECIAL FITMENT, PLEASE READ BELOW.
Originally there were some issues with fitment to the factory coil pack harnesses. The manufacturer has since resolved the issue, so ALL of the valve covers will now have a slot in the side (toward intake manifold) for the coil wiring to come out of. Previously, these were completely closed and we machined them.

Fits L83, L86, L84, L87, LT1, LT4, LT5, L8T cylinder heads - 5.3 - 6.2 - 6.6 - virtually ALL LT engines.
The lower half valve cover replaces stock valve cover. The upper half hides coils with holes for spark plug wires!
