inlet manifold bolt lengths

[jbuckl]

Please could someone state the inlet manifold bolt lengths?
reason:-
Taken an engine apart only to find the heads have been fitted with unf thread repairs instead of unc threads for the inlet manifold. will need to get some new bolts.... not going to change them back to unc.
Not near a stag at the moment to measure.

I’m away from base until this evening Julian but will be able to help then if you don’t get the info before then.
