Summits sales pitch. ?? Wonder how many companies are actually making lifters,

LOL, well, they do have a good description side bar so you can get decent information on something your looking at. AND, good question on lifter manufacturers.

This may be a dumb question, but, how much valve spring pressure and what kind of service are you subjecting them to?

Excellent question!
