Getting ready to reinstall my aluminium heads on my 383 and I don't have all the infos. about doing this right. Will be using new 170,000 PSI black oxyde ARP bolts. Cannot get their own moly or sealer . All the bolts end up in coolant in the 350 aen't they? So I have to use a sealer not oil or moly (on the threads) right? I intend to use Permatex liquid teflon is this good?
I'm confused about ARP recommendations of torquing/loosening 5 times a new bolt before final torquing!! How long should a bolt stay fully torqued before loosening and how long should it stay loose between the cycles..any important matter here? And will not the teflon expected effect be annulated by the torquing/slackening cycles?? It looks to me that the teflon once dried a bit will just loose its capacity if loosened/retorqued?
Finally my head manufacturer (brodix) recommends 70 pounds torque...ARP says for a 7/16 stud with oil 73 pounds and 56 with their moly...they don't give a specific figure for bolts with SEALER.....it should be different..
what you think,
thank you,Ronald.
