Double check that the alignment of pushrods in the tubes is still correct and that the upper rocker blocks are still centered on the sleeves.
When satisfied that PRT seals are fully seated and cylinder is evenly drawn up to the engine case, torque cylinder stud nuts in stages to 26 ft-lbs, using a crisscross pattern (10-4-8-2 o’clock, in that order). Use at least 3 stages (11-18-26 ft-lbs) or 4 (11-16-21-26 ft-lbs).
Do NOT overtorque.
