FS: GT40P Heads

I pulled them off a 98 explorer, put them on my car and it started to overpressurize my cooling system so I pulled them off and put the stockers back on. I do not know if these caused my problem or if it was a head gasket or a pocket of air, etc, but I did not have time to mess with it, my truck was stolen and I had to get my car running right again. $50 for the pair, they are un-milled and lightly ported. I would have them pressure checked and fixed before putting them on your car. PM me if you want them.
