My next flathead build?

[Ziggster]

The sludge is super thick in the valley. I can scoop it out with my fingers. Noticed the block isn’t relieved like my C59A block. Interesting also is the intake is different with the filler neck, and mine also had the crab style distributor. Not sure what you call this style distributor. Can’t see any cracks, and cylinder walls look good.
Next is to weld on a nut or two on the PS studs to see if that makes a difference in getting the studs out and the head off.
