706's have a bad rep due to issues with the foundry that cast them. If there is a battery logo on the head around the rocker bosses, they are the problematic head.
241's would probably be a better head. You'll start off with larger valve sizes and they don't have the issues with cracking around the bolt holes like the 706's do.
