If you replaced a stock head you increased compression pressure by 50%,you basically made a bigger hammer.Given the wear in your valve train I'm going to assume the rest of your engine is worn as well.Higher compression is the best thing you can do to a model a engine to increase power (that,and carburetion),provided its in good shape. Unfortunately you have to go back in and find the root cause of the noise.
