These Speed Engineering black valve covers fit LS1, LS2, LS3, LS6, LS7, and LS9 engines and give an additional 0.54" of internal clearance over factory height valve covers. The coils mount directly to the covers, which eliminates the OE-style coil brackets. The covers use proven OE-style baffles and vents, include gaskets, and come with one billet oil fill cap and 3/8" breather tubes. They work with factory or Speed Engineering spark plug wires.
⚠️ Important Notes:
