i have the heads off my mom's 96 mustang v6.. i need to figure out what size and thread the head bolts are. i've tried searching it on the net in tons of places and cant find it. i just need to find a tap or chaser to clean the threads and dont want to use the wrong one. im not the typical idiot and dont want to make ten trips to town to have the right info. if anyone knows i'de be greatfull.
