You can't determine the brand of the rod bolts by simply looking at the nuts.
They are Alusil cylinders and reusing Alusil cylinder is always a gamble. Those look especially rough.
There is an easy way to identify 6 bolts cranks by simply looking a the flywheel flange. Both 66mm (2.0-2.2) and 70.4mm (2.4-2.7) cranks have 6 flywheel mounting bolts but the 66mm crank has 2 plugged oil galley holes and the 70.4 crank only has one.


BTW: If you plan to actually drive your car/engine, get rid of the Dilivar.

Of course I recommend Supertec head stud but there are many to choose from. The best selling studs at Pelican Parts are Supertec.
