What is ok to use on my K-301 aluminum head and gasket to clean off the carbon?

do you follow the procedure here?
If so, when the last bolt is torqued to approx #15. stop.
Now they are all evenly torqued to approx #15
NOW:
Go back to bolt #1 and torque it to approx #25, stop.
Go to bolt #2 and torque it to approx #25, stop.
Go to bolt #3 and torque it to approx #25, stop.
Go to bolt #4, -- etc, etc. until all are torqued to #25 evenly, stop.
Now:
go back to #1 bolt and torque it to the given torque listed in the service manual,---- is it #30? whatever it is, go to that torque and stop.
Go to #2 bolt and do the same thing,continuing through all the bolts till all are torqued at the final torque.
Then follow the starting/ running/heating procedure I mentioned, and retorque one last time assuring all the bolts are at the correct listed torque in the manual.
You are tightening the bolts in steps, so as to not warp or break the head,
and insure the head gasket is compressed as equally as possible, to prevent leakage.
Most all engines do this procedure.
Clear as mud?
EDIT:
My old book says #25-#30 so I'd go to #30 on the 3rd step.
And again tighten to #30 after the running/heating cycle.
