Just remember before you go off and remove a lot of material from the deck on these:
These heads are of the "lightweight casting" variety, meaning the deck isn't as thick as on older, pre '78 heads. There is a fixed amount of material that may be removed, and remember that as they are, they're prone to cracking. Decking them will exacerbate this problem.
You're really far better off with S/R Torquer 305 heads if you want to liven your 305 up.
