I just recently bought a 91ex, I noticed when going over the engine that the block is stamped F22A6 which leads me to believe the engine was swapped at one point.
The engine has issues with either a stuck or burnt valve and I was looking to replace the head I was just wondering if there's any way to identify the head itself?
