ARP2000 kit tested to 750whp with Cometic head gaskets. These are an ARP Tundra stud that we break up into sets of 16. The thread engagement is not ideal, the studs are a bit short on the head side.

After having too many issues with head studs from other vendors, we had our own made. These are the ARP custom aged 625+ alloy with ideal shank size and thread engagement for the 2GR. Tested beyond 800whp with Cometic head gaskets and no block modifications.
