I just had my head rebuilt 400Km ago and everything's running pretty smoothly. So i called the machine shop that worked the head and asked when, and if, i should re-torque. After asking which gasket set i used (FelPro) he said Felpro headgaskets don't need to be re-torqued and that i shouldn't bother. I just wanted to ask here because you guys know this motor a hellofalot better than him. Should i re-torque? and if so, in how long? Thanks.
