Using these cylinder heads is a breeze. First, make sure your engine is turned off and cooled down. Then, carefully remove the old cylinder heads and replace them with these new ones. It's a good idea to have a professional mechanic handle the installation if you're not experienced. When it comes to maintenance, keep an eye on the engine's performance. If you notice any strange noises or a drop in power, it might be time to check the cylinder heads. For long - term use, make sure to follow the manufacturer's recommended maintenance schedule. Also, remember that to get full core credit, you need to return a good, reusable pair of cylinder heads without any cracks, warping, or excessive wear. Keep them in a dry place when not in use to prevent any damage.
