I dove in. Went really quickly until I couldn't get my plastic fuel line tools to work. Quick run to Harbor Freight and $7.91 later I've got a decent tool. No sign of cracks in the manifold. As you can see, the inside of the block passage ways are pretty dirty. No sign of corrosion on the knock sensors. Will order some fresh knock sensors and a gasket set and get it wrapped up.
