ive replaced probably 20 sets of v6 mustang head gaskets. did coolant get into your oil? does the oil look like chocolate milk? or the coolant? if they do, then you for sure did whats called a bearing wash. coolant got onto your main and rod bearings, and a layer of the tri metal bearing is now rubbed off. if it has, putting head gaskets in it is a band-aid, you will need at least a short block. i dont know your experience with cars, but if your not totally familiar with what im referring to, have it checked by a technician. better safe than sorry.\
if you only need head gaskets, i know some ford techs that will do it on the side for cash. i would love to do it, but since im turning a wrench for ford anymore, i dont have a lift. let me know what you find, and if i can help, ill be glad to.
