Exhaust thread again

[Lucky]

Hi

I am going to repair the exhaust thread in cylinderhead.
Is this the correct thread 1.997 in. X 14 T.P.I.?
I am planning making inserts of dural to replace
the crappy steel ones a previous owner had done.

B.R.

exhaust thread

1.997" x 14t.p.i. is the thread size and pitch,I would assume 60deg. thread angle.
