This is just a thread to summarise some info for those of us going flex and needing ARP head studs and to discuss where to buy in Australia.
I'll update this first post as new things come to light so it's an easy find for members looking for the info. Will also want help to fill in some blanks (in Red, if you can PM or post the answers or additional questions I'll update this first post for easy searching)
Fastening sequence I believe is:
7 1 3 5
6 4 2 8
Quick Info (10mm):
Quotes so far are not the cheapest but here they are below:
8740 material 10mm studs
From Sam at ARP:
If the block is a M10-1.25 thread, than I only have the 8740 Chrome Moly or the Custom625 (280,000 psi) to offer. This indicates that there are no ARP2000 material studs available to suit, despite what some of the ebay and online stores claim.
The CA625 stud number is:
AM4.500-10LB @ ~$38.27ea
Quick Info (11mm):
recommended by the geniuses due to higher strength, 11mm studs require the removal of the heads and tapping of the block to accommodate the larger studs. http://www.ozvr4.com/threads/how-to-re-thread-your-block-to-take-11mm-evo-head-studs.15338/
material info the same as above, but 11mm studs are significantly stronger
