It's pretty important. You might get away with it but it can cause issues.

The club has a tool to do this. It's worth borrowing...

it is little more than a lifter-block screw with a square-section head. you could very easily make your own......

The little bit more is a tapered section twixt thread and 'square bit'........when I changed my blocks I felt that I needed two of them. I did manage with only one tho.

I use the folowing method, all you need is a SHARP SOFT pencil :-
Snug down the lifter block bolts enough to stop the bolts "wobbling" but slack enough to allow the block to be twisted with moderate force.
Now twist the block clockwise as far as you can and using the pencil make a small line on the crankcase (From the lifter block flange out) in the middle Left to Right (as you look at the lifter block) of the lifter block flange and another that lines up with this one onto the lifter block flange itself (from the crankcase up). Next, twist the block anti-clockwise (again as far as you can) and now mark another line up the lifter block flange INLINE WITH THE PREVIOUS (ORIGIONAL) LINE YOU MADE ON THE CRANKCASE, now simply twist the lifter block clockwise again untill the CRANKCASE MARK/LINE is BETWEEN the two lines made up the LIFTER BLOCK FLANGE, torque up the bolts and and repeat.
Harder to write than to actually do.

thats a good idea, but im gona use a spacer that fits nice and snug on one of the bolts and just fits in the holes on the lifter block, shud be good enough.
