Valve seats (components in the cylinder head that help seal the valve) can fall out. When this happens, it causes rough running and creates noise. Replacement of the cylinder head is commonly required to fix this problem.

    No solution yet but ill probably try to buy a rebuilt cylinder head with improved valve seating to prevent further issues with this. Also, make sure all components to the cooling system are 100% because its often the overheating that causes the steel valve guide seat to slip out from the more rapidly heating/expanding aluminum cylinder head.
