I bought an 89 sc 153,000 miles for 500 bucks I noticed it was idleing ruff and "back firering" when you gave it gas the seller told me it was the exhaust come to find out it was the head gaskets. How do I know if the bottom end is gonna hold up if I just replace the head gaskets. Also there is a knocking is the super charger on idle and goes away when you give it gas what should I look for and what can I do to it as far as mantinence while I have it off the car
