Ok, so I got the SBC twistie headers, I got the gaskets to mount the headers. So what else do I need for smooth jet-boating? I know I need the thru-hull covers, but what about the water/cooling system? I'm leaning towards the Banderlog water control (saving my money). Once I get the headers on, how do I want to plumb this thing? Oh, by the way, anybody recommend a GOOD header bolt? Ok, so don't be shy, give your opinions.
