GT kit - a few pointers please

Have a GT200 kit to fit over the winter, just after a few pointers please.
1) The blanking plug for the head - do you thread lock it in? or is it silicon on the thread and wind it in?
2) Reeds - never had them before
- do I need to put a blob of thread lock on the screws that hold the petals? possibly a bit over kill or is it just drop them in?
3) In the guide it says " All head cowlings can be used but series 1 Li have the best fit" are they longer? I have at present the type with the extra baffle/plate inside which is if I remember rightly better for cooling.Just curious as to why a series 1 .
4) Head cowling again, if it needs to be spaced out between the mag housing due to the porcupine head, does anyone sell a spacer?
Sorry for all the possibly daft questions - just don't want to f**k it up
