Nut & bolt sizes?

[Seg]

Can anybody tell me what sizes the nuts and bolts are for the intake manifold. I need head and thread sizes not only for bolting to head, but bolting both halves together. One half seen here:

I am hoping to replace as many bolts and nuts on this cat as possible.

Thanks guys

No head sizes though - catalogue doesn't list them.

Thanks Ian. Very much appreciated.
