You will blow the head gaskets quicker with studs. Get ARP bolts. I have assembled a few sm mopars and the ones with studs blew head gaskets. I turned the studs between the threads to 7/16" and did not blow gaskets anymore. To much trouble to do that so I use ARP bolts and never a problem. Above 12to1 stay away from 1008 Felpro and Victor Nitroseal Head gaskets. Use Cometic MLS gaskets for 12 to 1 and up. 2 new and 2 used sets of ARP head studs for sm mopar 4sale
