If ya gonna run it to 24-25, I’d index flywheel on all six cylinders and check all cylinders and set it to highest running cylinder, almost always another cylinder is a little higher than #1. If not, I’d run it 22-23. JMO. There is a handful of threads telling how to index flywheel, if ya don’t already know how
