If you do change out your cam, ALWAYS go with new lifters. You'll find a ton of info out there on the matter. Use break in lube and a good oil. Since the oil companies re-formulated oil for better mileage, it's devastated alot of engine with flat tappet cams. You can find the high zinc oil just about anywhere now. If you're on a budget, Shell Rotella, Chevron DELO, and other oil made for diesel trucks, are good substitutes. Again, there's a ton of info out there on oil now.
