I don't think there is any one absolute source for early hemi parts. There are many guys around the US and around the world who specialize in them. Hot Heads, Bob Walker is probably the biggest, best known. http://www.hothemiheads.com/ He's helpful with tech on the phone too. PAW has an extensive catalog of parts - don't know how they are for tech http://www.earlyhemiengineparts.com/. I get my gaskets from NAPA. There is a guy here in San Antonio who has amassed a lot of early hemis and polys. Denver has one similar. There were multiple in Los Angeles. Others will mention other sources. Yes, all '51-58 Chrysler and Imperial plug wire covers are identical in length. Then all '52-57 DeSoto are identical length. And all '53-57 Dodge are same. But none interchange across the car brands because the blocks, heads and valve covers are specific length to the brands.
