What are you guys torqueing header bolts to? Anyone use Stage 8 locking bolts and do you apply anti-seize? I've watched a few youtubes looking for torque spec and not found any. What I learned is it's a PIA and so glad the motor is out of the car for this. I'm already in love with the R sound so I hope it gets better not worse, not sure its possible. And the Kook's look so good, seems like Ford would have used long tubes in the first place. With the engine out I'm staring at some type 4-3-1 manifold, shared with the CPC 2020 and certainly not cheap, but compared to the long tubes it just looks like it would better suit a CPC where long tubes are all matched length and should manage the symmetric pulses most simply.
