G`day ,

that would probably depend on your experience .

If you can drill a square hole and use a tap then it is fairly simple . ( pretty sure there will be how to on the net )

You will have your own way of doing it , whatever your comfortable with .

To drill squarely you can fit the other studs in their holes and use them as a guide for the angle of the drill bit , both ways lined up will be pretty much square .

There are of coarse other ways too .

I use Recoil brand because where i am that`s what can be found local , most nuts and bolts ETC specialists will have a kit .

The tap is not a normal size , so is special but in the kit .

When i say kit it only has the tap the tool to fit the coils and some coils .

The drill bit is extra and not in the kit .

The drill bit size needed to drill the block is either 11.5mm or 29/64 .

The thread that was in the block ( before it was removed ) is UNC 7/16 or

the ARP stud end that you fit into the block is UNC 7/16 .

The coils have various depths and are measured in mm .

As suggested if you not comfortable and have the option of a mobile bloke it may suit your purpose , i don`t have that option and the kit and drill bit may cost more than a mobile bloke , long time since i bought mine .

Cheers

Edit = when i typed square hole i think i meant hole square as that make sense .

The updated instructions for head studs from ARP is to 70 foot pounds. Pedro went 100. I emailed ARP and they told me the studs would break at 100... I would be wore worried about threads in the alloy before worrying about hard steel. Cheers
