It was 155 across but #1 cylinder wouldn't hold ANY compression. I figured I popped the head gasket as it is an oem composite, with arp head studs, and I've been running 27-28 psi so it could happen. The car is now all torn down now, pulled the head tonight and low and behold, several head studs around that #1 cylinder are wobbly as can be. They backed out some how and it only took 3 turns to unthread it, they were barely in there.
how many times you had em out and back in?
You have to crank em in with the allen key several times over before putting the head on and torquing them down. crank them and let them settle for 10 minutes then go back over. they'll walk out due to the displaced air/oil in the hole that gets pushed out by the stud when you thread it in. gotta keept doing it to squeeze it out or the pressure will push them up.
