I may have messed up here.....

Garth,

At last the bare block is with the builder! He has measured all the clearances, crack tested and sonic tested everything and declared it sound. As soon as I know all the final numbers I will post again.

One thing that came up and slightly surprised me was, even though we’re going from main cap bolts to studs, that after measuring everything no line hone is needed.
Everything I’ve read says that honing is required after converting to studs, but I guess if everything’s torqued up and all the holes are still concentric then all is well? Does that sound right?
The studs came as part of a Hughes girdle kit which he is not keen on using! Not sure I completely get his reluctance, but I’ve posted about that here:
Hughes main stud girdle - yes or no
I’d welcome your thoughts!
