2.7 Crank sticking

[Cookies]

Hi, looking for a bit of assurance…

I had the case halves, crank and line bore checked at the Headshop Warrington. Advised standard shells. 

On mating the halves and torquing down the long bolts 25 then 35nm the crank turns by hand at 25 and then sticks at 35nm. I can turn it easily using a socket on the belt pulley but it’s not moving by hand. 
 

on the plastigage there is one that is a bit tighter, picture attached.

I’m not wanting to go further, if this sticktion is a bigger problem.

What problems could one tighter fit cause?

I wouldn't proceed with the build until you understand the cause of the tightness. I'd want to be able to turn the belt pulley by hand when torqued.
I'd start by removing the crank and shells and making 100% sure that there isn't even the slightest bit of dirt or debris behind one of the main shells. It wouldn't take a lot to make one journal tight. There'll be a witness mark where any debris has been compressed between the shell and case. Both surfaces need to be clinically clean before fitting the shells.
Are the bearing shells from one of the quality German manufacturers ? Could they have been dropped or damaged prior to fitting ?
If it's not the shells, then its got to be either the case or the crank. Has this crank and case combo run as a set before ?? How was the crank transported back from the machine shop ?

Thank you…. It’s what I needed to hear.

Didn’t want to pull the case apart again.

not unusal on a mag case. Only solution I believe is to have the cases pinned.
