Oil Pan Removal & Reveal

That 394 pan might rub the K-member. As mentioned, remove all the paint off the crank flange. I don't know which torque converter you're using, but, if it has the big button that matches the crank hole diameter, it might not slide inside with the paint in the hole. If you're using the '65 904 converter, you need to get the reducer bushing to match the small button on those converters. I'd also weight all the flex plate bolts to be sure they all weigh the same since they're a mixed set. Oh, and did they really weld the rod nut to the bolt in that one photo? Yikes!
