head stud thread size..

[Adriano]

I need to buy a tap to clean-up 2 holes on my 6-bolt block. Does anyone know what's the thread/pitch size of the head studs? Thanks

I did some looking around, and it appears to be a 12 x 1.25 thread.

A tap that size is hard to find, I had to order one online.

I got one today (12mm x 1.25) There's a machine shop supplier by my house that has ANY size tap available in stock. It cost me $8. Thanks Mondo for the size. \
