Rick, thanks. I'm using the Edelbrock heads. I didn't know specifically why, until you mentioned it, but I knew I would have to machine the heads, get new pushrods and pay additional monies for the T&D's. I think the added cost is somewhere in the neighborhood of $500-$1,000 extra, which isn't by itself all too horrible, but when you add it the rest of the engine...Ugh.
