[RESOLVED] Head stud/bolt hole threads

[b00stedtalon2]

Need to know the thread size of the head stud/bolt holes that are in the block so I know which tap to buy. I plan on using a tap to clean the threads before I put my head on. Thanks

1g diamerter is 12 mm
2g diameter is 11 mm

the pitch is 1.25

Yeah, the 6-bolt, 12mm stud is definitely 1.25 pitch.
