9/16" head stud conversion

Hi,

Just wondering if anyone in australia has done a 9/16 head stud conversion?

 

Its probably a bit of a waste of time as the up grade is to head studs (ARP) than use bigger bolts.

 

I'm sorry but I don't understand? What is your suggestion otherwise?

My options I see are

L19's
Standard arp
Oem head bolts
9/16 big arp head studs

?

 

What I was getting at is there is an ARP upgrade kit that is the same size thread as the stock bolts. This is what most people buy for an upgrade.
