Header Bolt Size for OHV

I had a hard time finding the correct size of bolts to replace the studs on my headers, I pulled a bolt earlier today and found that the size is M8 with a 1.25 pitch at about an inch long.

I used this length bolt for Pacesetter Headers in stock heads.

Hope this saves someone some time.

Header bolt size: M8 1.25 24mm
