Well i been overheating, spitting fluid all over my engine and getting crappy heat. I tryed a couple things... Water pump, radiator flush, rad. cap, thermostat, and checked my heater core and STILL hasnt fixed the problem. I was going to do a comp. test but i found a guy trying to get rid of soem heads cheap. So he wanted 100 for them, i offered 50 and took em home that day. They are clean and everything but my question i guess is. After this . Should the problem be fixed or am i looking in the wrong direction? - Thanx guys
