That cam should be the P 4529341. Hydraulic .420 lift 250 dur. It really does not require dual vave springs. As for pistons, are you sure they are domed? Domed pistons have not been available for the slant six (except for custom racing units, high dollar) for many years. What is your compression ratio? Most domed pistons would give a nominal CR of about 12-1. With that cam, you don't want the CR too high. 650 carb is a little big, but being a vac secondary, will be more forgiving. All iron block slant six engines are closed deck, only the aluminum slants were open deck.
