Well.... I thought I had the vac advance problem. I had about 8 degrees initial and when plugging vac advance in it looked like it went to over 40 degrees advanced at idle! I have an adjustable vac advance canister so I backed it all the way out. I adjusted my initial to about 12-13 and adjusted the vac advance to add another 12 or so. After that I adjusted my air/fuel and idle on my carb. Done all this in 5-10 minutes while keeping an eye on my temp. It still crept up to 230 in that short period of time  . I borrowed a hydrocarbon tested from a friend tonight to test my coolant. Afraid I have the head gasket issue. Makes sense because my setup ran for hours three or 4 times but, since I drove it for an hour and it got hot it overheats within 5-10 minutes idling. Even faster while driving...
