considering I messaged you concerning W8 intake gaskets awhile back.... I find it hard to believe you went this route. I know the guy that bought one of my top ends is starting to assemble, so I'll let him know. W5 isn't even a good place to be from in my experience.
If I ever find a virgin blue plug I will tread carefully in known water areas, sonic check often, and weld up other areas for needed volume space. I will also pour the water passages with (WaterGlass) to address porosity issues
