Our laser cut rail valve covers are perfect for all SBC motors that are looking for a strong reliable valve cover. These valve covers offer great performance while our unique looks give your motor an edge in appearance. These valve covers are designed to withstand the repeated installations and removals often necessary on race engines. These valve covers also include pvc port holes on each cover and a fill bung with billet cap on the front of one cover. The 5/16" laser cut rail provides an ideal mounting surface while the .100 aluminum fabricated upper keeps the cover ridged and light.
