APE cylinder head nuts

[Katzukes]

Has anyone had a problem with the #1 and #3 nuts on a gs1100. I have APE studs and the nuts won't slide down the recess. I tried another head and it's the same thing. What can I do to make it work.

on 80-83 1100 16v. engines you only use 6 of the HD nuts.
4 factory nuts on the corners(valve cover) and the 2 front center factory nuts with the o-rings.
on an 1150 head you can use all 12 HD nuts.

Thank's, do I torque all the nuts to the same value.

The APE nuts are torqued to 36-42ft lb, do I also torque the stock nuts on APE studs to APE settings or Suzuki torque values, which are 25-29ft lb.

38lbs on all nuts for a carbureted engine sounds good.
i have went 45lbs on my turbo set up's but on customer bikes i always used 40lbs.
there is a fine line on pulling the threads out of the engine case.
