Yes, another lurker, 
         My thought too. Why couldn't a special retainer or different
keepers do the job. My other thought (not having seen a 2.3 valve in 12
years) was there might be a groove under the keeper groove where a
non-interfering square cut seal could be inserted, ala Chevrolet. My
feeling also is that something different must be done in order for that
cam to work. I agree completely with the dial indicator and measuring
department and their figures. But I also believe there ARE non-intrusive
ways for that cam to work without major modifications.
