289 cylinder head on 5.0L????

[FiveORacer]

I saw an article on using early 289 cylinder heads on a 5.0. These heads don't have the thermactor bumps in them and have a much smaller combustion chamber.

Since I have 2 sets of these heads and no cash for anything else, I was wondering what pushrods and rocker arms I use with my roller cam. Do I use the 5.0 stuff?? The stinkin article didn't use a roller!

Has anyone done this? I'm looking for better sound with a cam that I already have. Next year I'll go with better heads; this is just for the sound this season when we cruise into the ice cream stand parking lot.

Thanks for any help!
