Keep The Valvetrain On Track
Valvetrain components such as lifters, pushrods, rockers and valve springs are often replaced when rebuilding stock engines. Worn rocker arms and lifters should not be reused to prevent failures down the road. If you’re installing a new flat tappet cam, new lifters are a must. Any pushrods that are not straight must also be replaced, along with high-mileage valve springs that have weakened with age.
