Sounds good to me with that new cam & lifters, there's plenty to choose from (Harland Sharp, good quality & not over priced) use 1.5 ratio & some hardened pushrods with guide plates & new studs, but determin what size studs you have either 3/8 or 7/16. You shouldn't need any head mods except taller valve covers! having said that any head work with those mods would be a real benefit, & don't forget that timing chain.
good luck & fry them tyres!!
