i need help with figuring out the thread size on the bolts that mount the coolant crossover tube to the cylinder head. i purchased a brand new set of take off 799 heads for cheep because the threads are stripped in one of the bolt holes for the coolant tube. i plan on fixing this by installing a heli coil but i need to know the thread size first.

get a thread pitch guage and check one of the bolts that will tell you the pitch of the bolt and if you dnt have a bolt take your other head and check its pretty easy
i had this happen to me dnt remember pitch though good luck and you may be able to chase it try that first

take on of the coil bracket bolts (the ones that bolt the bracket to the valve cover) off and too Home Depot. they are the same size bolt and thread, give it to the parts dept and they will tell you what it is.
