What is the differents between the 1.2 and the 1.3 if the 1.2 was bored out too 1.3 would it go just as well or do they have a different stroke ect?

1.2 is the bigger bore, 1.3 has smaller bore with a longer throw crank.
Search out topics on 1400 big bore conversions.
As above. 12ST block is also shorter than 13SB.
14nv block, 12st pistons, 13sb crank and rods if you want a fun motor.
What compression were you at on yours & what head were you running? I think an NV block is also shorter than an SB.
I have a 13SB block & pistons, 12ST Mahle pistons & C16SE head. Just need to get around to building it. The 13SB block is taller than the 14NV so compression should be slightly lower. Would be interesting to see the comparison in height between 12ST and 14NV.
