Default spark plugs

Hi guys i am looking into changing my plugs in my BOSS.It's due for some plugs I have the standard heat range at the moment.What do you guys recommend.I vaguely spoke to Chris about it a while ago but can't remember what brand and heat range i should opt for.I think there a 5 now so if i go with a 6 will it need a re-tune after changing the heat range or will it be ok.

It depends greatly on the build, from memory Alex your combination is a fair bit higher in compression than we are used to, an NGK6 range is for stock GT, so I would think at least a 6.
