iani Posted December 13, 2019 Report Share Posted December 13, 2019 For those of you who have used ARP head bolts, have you retorqued them or not? The manufacturer states: "Do I need to re-torque my head bolts or studs? If you follow the ARP installation instructions, there should be no need to do a re-torque. However, it may be necessary under certain circumstances if the gasket manufacturer’s instructions require it, particularly if a fire ring has been installed. ARP recommends not doing a re-torque on a hot engine." My engine builder says I should. Quote Link to post Share on other sites
Motorsport Mickey Posted December 13, 2019 Report Share Posted December 13, 2019 Although the ARP are fine the gasket needs it if a composite, to take up “ in use annealing” and relaxing. Mick Richards Quote Link to post Share on other sites

Nigel Triumph Posted December 13, 2019 Report Share Posted December 13, 2019 Retorquing is even more important if you have a recessed block engine, because of the gasket's fire rings that sit in the recesses around the bores. Nigel Quote Link to post Share on other sites
Peter Cobbold Posted December 14, 2019 Report Share Posted December 14, 2019 TR6 gasket (Payen) seals with heat-activated resin films and should not require retorquing. However I do...belt and braces. Quote Link to post Share on other sites
