Small Block & Big Block Chevy Specific - timeing chain cover

im looking for a timing chain cover for a pontiac 301 motor anyone no where ican find one ?????????

enginequest.com has them thats were i got mine for a 400 i built I do not know if it's tge same as a 301 but i think so why the 301? is it a turbo mill? I just never really had any luck i took out the 301 and set it off too the side to keep and dropped in a 400 the enginequest parts are New, sometimes they also have used stuff in stock but i'd go new
