Hi Gordie, The 1622 block has a very high chrome content for long
life. It is not compatible with chrome rings for the very reason of slow
or NO seating. Use plain cast iron rings and it should seal up. A friend
rebuilt a 1622 in 1980 and it took 3000 miles to seat the rings and only
then after it ran on the verge of overheating for a 100 mile trip. Ford
F150 trucks had the wrong rings factory installed at one point in the
70's. The dealer "recall" fix was to pour less than a 1/2 teaspoon of
"Bon Ami" cleanser into each plug hole.I've never tried this but it
apparently saved Ford lots of money.
