The real waste of potential with the elebrocks is not going ahead and putting them on an engine that will yield at least 9.5:1 compression with them installed. Of course, a properly selected cam will make or break a low compression combination. But a set of zero deck flat tops with no valve reliefs and some thick cometic gaskets for piston to valve clearance would just be better all the way around. And regardless of what you do, I highly recommend the B-3 racing engines rocker correction too. You email them and they will give you directions on how to measure your rocker gear and they will make a set shaft spacers that correct your geometry. It may appear to be overkill for your build, but it's money well spent.
