Leads are leads but many workshops will recommend using the OEM leads supplied by Holden. Good enough for turbo/blown cars etc.
Plugs are dependent on what's done to your car. 2 types that are frequently recommended are:
NGK TR6 (slightly colder plug)
NGK BPR6EF
Both of these willl be more than adequate for the job.
Research BRISK LGS if you want to try something different. GOR-15LGS
MSD leads are supposed to be the best in the market.
Try Magnecor KV85 leads.

BPR6EF-15's are cheap and effective but require regular replacement(15,000Km's)
With the alloy heads is there any issues getting out the original plugs that have been in there for 80,000km and maybe 4 or 5 years? You wouldn't want to stuff up a thread in the alloy head. Might also be a consideration when chosing a plug as well, maybe a long life plug might be the go rather than changing them every year has anyone had any problems getting them out?
I was just thinking of how alloy and steel sometimes react on one another.
Magnecor race leads $180/set and NGK Iridium plugs (100,000km life) $18 each.

As chilly says, a bit of lube on the threads and they come out easy.
Once you have done a couple it is a 30 minute job at most.
Always change my plugs when the motor is stone cold also.
Running the NGK Super six plugs here as well, change them
every 10k for peace of mind.
If you change the plugs every 10,000km @ $25/set = $250 for 100,000km.
Each time you remove the leads you also risk damage to them, especially as they get older.
1 set of Iridiums = $144 and it lasts for 100,000km.
Some people do not keep their car that long, so it means they would only ever change the plugs once.
If you pay a mechanic to change them each time = more $$$$
Each to his own, but I use Iridiums

spot on mate
now lets do the oil change at 3000 k's...or 5000 k's x 100,000 = $$$$
but i for one am happy doing this with the extra cost as it gives me peace of mind
my car has done 150,000 k's with the same auto...
last 2,1/2 years with head/cam etc
but i change the fluid every 15-20,000 k's....
have i gained anything....i think i have..
