ARP Cyl Head bolts - retorque?

Recommended Posts

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.

 Although the ARP are fine the gasket needs it if a composite, to take up “ in use annealing” and relaxing.

I thought as much Mick, another job for the list.

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.

TR6 gasket (Payen) seals with  heat-activated resin films and should not require retorquing. However I do...belt and braces.
