  Hi what head gasket kit should I run for the IAG stage 2 block. I’m confused because it comes with oem 99.5 bore but all the head gasket kits are bigger bore like 100. Also what thickness? Can you give me a link or part number for the full head gasket kit please? Thank you.

    A:  IAG recommends using OEM head gaskets with their open deck blocks. We would suggest contacting IAG directly, or your engine builder to see what they recommend.

  Can I run oem head bolts or do I have to run upgraded head studs? If I have to run upgraded head studs which ones screw right in? I already have this IAG stage 2 short block in my possession but my oem heads are getting sent out to be machined, valve adjustment etc. please let me know what I can do. And what I should do. Thank you. I appreciate your time.

    A:  You can use the OEM head bolts, but the ARP 11mm head studs would be a recommended upgrade.
