Tony, Valve covers for 56 and 57 D500 Hemis are the same. They should have bumps for clearance of the exhaust rocker arms. A few Dodge 315 Hemi trucks also used these covers until 1959. The spark plug covers had notches to clear the bumps. Only the 56 D500 engine had solid lifters, which require the bumps for clearance of the adjuster screws. In 57, D500s went back to hydraulic lifters. Once the tooling was modified for 56 D500 Hemi covers, it was not changed back to delete the bumps when they were no longer necessary. If you cannot find the correct covers with bumps for your 57, you can use any Dodge Hemi valve cover from 1953 to 59. Poly covers will not fit.
