Take a compression test. If its low, you will need to rebuild the top end. If possible, before tearing it apart, perform a leak down test as well. This will tell you the condition of your crank seals and gaskets. If you have a bad seal causing a lean running condition and don't fix it, your new top end won't last very long and you'll be rebuilding again in no time.
