I would NOT run those heads. I've heard nothing but nightmare stories about Speedmaster products. For a few hundred more, you can get a pair of AFR small bore Enforcers that are designed for 5.3 sized bores and outflow 243 castings. I just bought a pair of them myself, and they're nice.

I'm still gathering a few parts to start building mine, but yes, you can use stock rockers. I wouldn't use stock pushrods with any performance build. If you mean stock length, possibly, but you should always measure to be sure.
