440 ordeal continued

get a plug adapter for a vacum gauge. air up the cylinders with a compressor 1x1 with the piston on compression stroke. listen for where airs going thru xhaust or thru intake. loosen offending rocker to see if leak stops. do this on all 8 and then check for compression as this should allow valves to seat . turn motor over first with torque wrench first at damper with 15 ft pounds and plugs out to check for interference. install plugs if no piston to valve contact and fire it up. should run as long as valves are seating you may want to give an xtra turn out on each adjuster to allow for heat expansion.
