Manifold to Head bolt size

[Anonymous]

does anyone know the bolt size and thread? I need to drill out and retap an exhaust manifold bolt (ie. the bolts that attach the manifold to the head, not the studs that attach the manifold to the pipe).

Ummm...not sure on US head but my Oz head is a 3/8-16 on the exhaust manifold bolt holes

If that is the correct size then that is what the Us head is also.
