The 318 went roller sometime around 85, your 88 should have a roller
cam. But even if it doesn't, modern oils are just fine for such a mild
low-lift cam with soft valvesprings. The zinc scare is somewhat
overblown- its only a real problem with huge muscle-car cams that
require concentric valve springs with astronomical spring pressures.
