valve clearance is .014 inch for intake and exhaust with engine warm.
head torque it 21 ftlbs, then 44 ftlbs, then loosen all, torque to 89 inchlbs, then to 21ftlbs, then mark and turn the bolts an additional 60 to 65 degrees.
cyl head sub bolts torque 80 to 100 inchlbs.
thanks.

to "fix" a head gasket requires taking off the cylinder head and associated compnents, getting the cylinder head serviced to ensure flat surface and no cracks, reaplcing the head gasket, and reassembly ensuring the proper torque of all bolts, especially head bolts........what makes you belive the head gasket requires fixing

If you are talking about the pressure plate to flywheel bolts, the torque is 16 to 22 foot pounds.
