Gen V LT Two-Piece Valve Covers – Smooth Finish with Hidden Coil Mounts

Description

***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. However, these are not machined properly to fit the Gen 5 coil connector, so we machine them more for proper clearance. SPECS:Gen V LT “Smooth” 2-piece valve covers, SIMILAR to Holley’s 241-182 for LS. 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.
