Heads On
Got the heads on!
Sharp eyes will note that the long studs are ARP replacements and the short studs are stock Porsche. I'm sensing a problem with one stock stud as it's really soft when being tightened. The other stud is stiff. I'll check for another stud to replace it. I'll be doing a few re-tighten cycles before adding the cam towers.
The ARP studs have a torque spec of 100ft-lbs. That's a lot. They've got a finer pitch, too, at 1.25mm instead of 1.5mm on the stock studs. With their fancy lube, those things are super tight. I'll be using 2 90 degree turns on the stock studs and considering how it feels.
