Does anyone know the size and pitch of the exhaust manifold studs, the ones that connect to the down pipes? This is on a 93 motor. I messed up 3 out of 4 internal threads in the manifold. Can I repair the threads in the manifold by chasing them with a tap or has this stud completely ruin them, if not what else can I do?
Thanx
