When the head was worked on did Engine Lab replace the valve guides? Alpha said he didn't think so but it would be nice to know for sure.
Maybe the guides were installed too high or non oem seals were used that are a little taller? If you could get ahold of two pro series retainers we could also check the clearance pretty quickly.
