I installed a complete set on a Genesis (cast caps) in 2012. The only issue I had was after fitting the caps in the bulkheads, align boring and align honing when completing final assembly the rear main cap would not seat in the block. After much fiddling I determined the seal groove was not cut sufficiently deep. I called Program Engr. and they advised me to return the cap. Two weeks later the cap was returned to me, without comment or explanation, but did installed as expected. I called Program Engr. and was told "they just messed up on the final depth cut". There was no charge but that doesn't exactly inspire confidence in their product. Pay attention to Program Engr. interference recommendation at the parting face in the bulkhead.
