According to Sessler's data book, casting 1852029 was produced in 1962 and 1963. Is your block date stamped '62? I'm presently rebuilding two 413s, a 1852029 & a 2205697. The 1852029 seems to have a more pronounced support webbing. Let me know if you plan to go with a 4.25 bore, as I have a set of 426 pistons that I will probably not be using - I'd prefer to spend the coin to get new ones with characteristics that work for my intended use. Good luck!
