Questions about BPC4082CTC 408/375hp

Not sure what a 1971cy is? lol. But here’s the engine. Pardon my cluttered mess in the garage. I’m going to use a set of vintage Gardena Ca Cal Custom valve covers and will be repainting the engine soon. I know the stripes are not correctly placed or correct period for a 72 Twister. But it is an A51 car on the fender tag. Not that means anything or important for that matter. View attachment 1715880993
