Got the Poly 318 Heads Redone...
Got the heads back from the machine shop today. Hopefully this will fix the overheating problem. Painted them with Chrysler Turquoise (or green; whatever they call it). I noticed with the new head gaskets that there is a 3/16" hole where there is a 9/16" hole in the head. That may be one reason for the heating problem. I don't know if it's the same for the heads and head gaskets that are currently on the 318. I guess I'll find out tomorrow.
