Texas Speed & Performance valve covers are machined from a block of billet aluminum. They are 1.5 inches in total height and will come with new rubber o-ring gaskets, as well as the necessary hardware to bolt them onto your cylinder heads! They will use a push-in style valve cover breather with a rubber grommet, and the opening is 1.25″. They are designed to help clean up the look of the engine compartment, so they do not have coil mounts on them. You will have to relocate your ignition coils and run custom-length plug wires.
