Good hot soapy water and get after it. Take some old towels to dry things off and a can of WD40 to spray the inside of the dist cap and points if it doesn't start back up. Driving it there to get the engine good and warm will help too. I'm sure others will chime in with their suggestions.

There's a high view count YouTube video where a guy swears that brakekleen does a fantastic job. Cant verify that myself, but I intend to do a small-scale test on some parts or a lawnmower or something.

Brakekleen will eat the paint off anything it gets on. Use a chemical designed for engine cleaning. Your parts house and Walmart will have several selections. Harold

Repeat as necessary. Jerry

I'll also look at commercial "gunk" which is pretty effective but only on hot parts. Will leave feedback on how Im make out. Thank you.

Stick with the common store engine cleaners, some good biodegradable ones out there that will cut grease and grime but leave paint alone.
Watch out on a pressure washer as they can damage gaskets if to high a pressure, (specifically cover gaskets)

Good question, I purchased the truck as-is. Don't know why they didn't at least thoroughly clean/paint the engine when the frame was being done. I'm holding off the engine re-build for now, just wanted to clean it up.
