Unfortunatley, issues have grown. I fixed the water pump stripped hole easy with a thread insert ($27 kit at Ace). But, when I held an intake gasket against the manifold, I find where they drilled the bypass hole is off and partly overlaps the gasket sealing surface. I wonder if that is why that intake was sold affordably on ebay, perhaps others noticed the oops or the seller stated it and I missed it. Someone skrewed the pooch on that mod. Sometimes you will drill a starting hole fine, then expand it and find the later drills changed the centerline. Best to have parts clamped in a drill press or milling machine to avoid that, but takes a lot of setup time on an angled part like this. Not sure why they thought they needed such a large hole anyway, greatly overthinking the engine designers.
