What is avalible for pistons and rings? Who has them avalible? Head gasket too? What is the stock bore on the 300 jug?

An 85 odyssey 350 head gsaket is a real close match and last time I checked the base gaskets were still available from Honda. Here is a couple pics comparing the gaskets. They are identical except the bore on the 350 one is just slightly bigger. The stock 300r one is the copper one.
