Forgive if this information is out there already. I've done multiple searches and none of my keyboards brought up anything.

For a 408 build up with a new iron block do I need this part number ARP head studs, 234-4317? 2004 and up blocks have all the same length studs, correct?

Went to pop in the studs we'd purchased for the LS1 motor before it bit the dust and no go.

Thanks.
