Is it worth adding drain valves at the ends of the exhaust manifolds? Putting in a brand new set of Barr manifolds, and thought about adding a Fumoto valve at the far end of each for easy draining instead of the supplied threaded plugs. Not sure how much water might or might not stay in them when the block is drained. I'm assuming the block drain, really doesn't help the manifolds drain but a little bit. Thoughts??
