Does anybody know the size(thread and lengths) of the studbolts used on the intake and exhaust manifolds?
I have plans of replacing some parts, and since these break far too easy since they probably havn't been touched for 30 year, a way to get some quicker than Simon is preferable.

Hi,

Exhaust M8 x 1.25  x  approx. 45mm

My local Motor Factor Supplied total length 45mm with 22.5mm length thread one end and 12.5mm length thread the other with a 10mm length unthreaded bit in-between which did the job.
 

Inlet M7 x 1.00 x approx 45mm.  Similar arrangement as the exhaust regarding thread lengths.

Cheers,

GP
