I know someone's mentioned it here before, but the good ol' search wasn't working for me. Can anyone help me out. I need to chase the threads since not all of the headstuds are threading smoothing.

Many thanks.

Edit: 'doh, checked my helms and found it: 11x1.5mm

Thats for a D or a B series engine?

 

not sure about D, but B series is 12x1.5


on the other hand I think it's 12x.1.25...

it's one or the other. I haven't chased them in a long time. Let someone else chime in
