Hi,
I have a set of heads that have been sitting around for about 15 years. I believe they are Dart II Sportsman heads, but the intake and exhaust castings are very rough. Doesn't seem like an aftermarket head would be this rough. Anyway, I'm going to port them. I just need to find out what heads they are to know if I want to use them or move on. They have 2.02/1.6 valves, triple valve springs with guides, 64cc chambers, at least they look 64 by the shape. Your help would be greatly appreciated.
