New rockers and pushrods. I also went pedestal to save money from having to buy pushrods... I ended up needing them anyway. Do yourself a favor and just bite the bullet and get stud mount.
Steve, its actually best to NOT buy pushrods until the heads are on the block and you can check geometry. Buy a pushrod length checker and checker springs. They are not much money at all, use them to check the length you need and then buy your pushrods. Most do get away with the stock length with AFR's, but its always good to check.
