Unfortunately as of today as i was going to clean out the head and lap the valves, i discovered a crack between the sparkplugwell and an inlet valve in cylinder 2 and 3.
So i guess ill be needing a new head. The rest of the engine looks REALLY good, pistons, walls, cams, rockers etc.
What head will be my best option?
I've read that a GSXR1100 (86-90) or GSXR750(87-89 short stroke) would be a good improvement cause of better airflow.
Are one of these a straight bolt on or what should i be expecting?
