Inlet manifold bolts

[grb184]

Hi, Bit of an odd query, I currently have a cable throttle linkage which has a backet which a previous owner has bolted to the inlet manifold bolt, I would like to replace this and thus the manifold bolts themselves.

I have been searching the interweb and have been unable to find the size and pitch of the intake manifold bolts so when I remove the current Heath Robinson design I can replace the bolts to look like standard.

Can anyone please tell me what the sizes are for the Intake manifold to block bolts are.

Thanks

They're M8 std pitch. Not sure how long... 25mm?
