While driving last Friday, I overheated and El Stupido Grande me didn't stop and let it cool. It blew out the head gasket and made a deep scar betweem 3 & 4 cylinders. I have to take the head to the shop and get it surfaced now. I didn't want to do that with this mostly stock A12 head. I have had nightmares with the distrubutor. I have put in every distributor that I have and they all are screwed up. When I ordered the head gasket from Advance Auto, I asked them to look up an electronic distributor just for grins. I had done this a few times in the past and they came up with "not available." This time, the 79-up were still not available but the 78-below were. I had it in hand the next day for $110 + tax. It is rebuilt but has all new insides. Hopefully this will cure my overheating problems. I will take the head to the shop today and get it back tomorrow. I'll keep ya'll informed.
