The heads on a 1998 and 1999 V8 5.7L engine are generally the same, but there may be some small differences between them depending on the specific make and model of the vehicle. It's always best to check the manufacturer's specifications for your specific vehicle to ensure that you are using the correct parts. If you are in doubt, you can consult a mechanic or a specialist in your area who can advise you on the best course of action
