I’ve got a 1.6tdci says to do pretty much the same if not the same but what’s classed as a short bolt and what’s classed as a long on (Iknow it’s sounds stupid tbh im still learning)

 

thanks for any any help or information 

Exactly as stated-
The short bolts are short, the long ones are..... [emoji848]

Sorry, couldn'y resist.
It really is that simple.

Ino it’s stupid I’ve only ever done heads and they’ve had the same size bolts every time 😰🤔 Now I’ve had a good think I’d class them as long 😂😂😂😂
