390 w/open chamber heads

On the pushrods - do not assume the stock ones will work. Even if you're not square decking (which I totally disagree with) the differences in factory machining even side to side, plus the work on the heads, plus the necessity of setting the proper preload with the rockers - you will need to measure for the right length (or lengths depending on how messed up the deck is) and then order them. Pushrods are always the last parts I order.
