Those seem a little on the high side for a flat tappet. Good thing you checked them over.
Andy , if you are concerned with the pressure how do you feel about Hughes requiring 155/415 spring pressures ? I am running 130 seat with my Iskys (8305?) at the moment . And am looking at 135-140 for my new motor. Solid FT cams
