some one said i need a new engine, because the heads in the car are made of aluminum. The car heats up when you hit 80mph. If you go back to 75mph it cools down. Also when your driving it has a little hesitaton. I have to put in antifreez at least once a week. Can the heads be replaced??

The fault lies not with the heads, but the bolt threads in the block. It should be determined that an internal leak exists before worst case is assumed. A cooling system pressure test, as well as a block test for combustion gases in the radiator can confirm a leak. If it is determined that an internal leak exists, the block can be repaired with thread inserts.
