Pulled the heads today. This engine had been rebuilt before; clean inside. One of the first things I noticed was it had 624 heads. They have 1.72 intake valve head diameter. I will be upgrading to 1.94’s or 2.02’s. Also, one of the exhaust valves was sunk. Pulled the oil pan, and discovered that it’s a 4 bolt main! Hopefully, all I need to do is re-ring and new bearings. Before then, of course, I will have to put an intake/carb/head package together.
