Most flat top pistons have notches cut in them to clear the valves. You could cut the notches deep enough to suit your cam or get a cam with less lift.

What causes water in the exhuast?
There are basically 2 causes. One cause is condensation which is normal. This is the hot exhaust hitting the cold parts causing water to accumulate. It goes away after the system warms up. The other cause is a blown head gasket which is very serious. If the water smells and taste sweet, it is coolant and you have a blown head gasket. Stop driving the car immediately and have it repaired. Other signs of a blown head gasket are coolant in the oil, air bubbles coming from the radiator inlet with the cap off.
Why is there a loud crack crack crack like a stone hitting metal from the back of the car near the exhaust when the engine is turned off and cooling down?
Your hot exhaust is cooling down and the metal is making a ping sound, chances are though, that your exhaust is possibly getting too hot, or has some loose components inside or bolted to it. If your exhaust rattles at all, you may need to replace the muffler, and if you car has a trouble code related to misfire, or catalytic converter there may be too much fuel in the exhaust and is too hot.
