So I need to replace my cylinder head on my 2006 FZ6. It's no good anymore. I found one on eBay but it's for a 2005 FZ6 and mine is a 2006 model. Will this cylinder head fit my bike?

Ok am I the only person wondering what happened to need the cylinder head replaced. . . . .
Ok am I the only person wondering what happened to need the cylinder head replaced. And I have no personal knowledge but I thought somewhere on here they decided the intake ports were to different on the r6 head to work with our intake system which up must use due to the frame design. But a few people have used R6 cams in FZ6 heads
So it needs to be replaced because one of the valves went loose and hit the piston and part of the cylinder head. I really want to know why that happened.. The mechanic says it cause the oil pump stopped working and the other says it's because the cylinder head is not working properly. It doesnt matter what it is because the cylinder was scratched when the valve hit it so it needs to be replaced. This is the second time it happens and its the same valve that goes loose and hits the piston. luckily last time it didnt hit the cylinder head. NO i dont race it or stunt the bike, i just use it to go from my house to college. I really like to take care of my vehicles but i just dont know why it happened again and why the same valve. a friend told me it was due to the timing not done right but idk. I want the bike back already!! so i need to find a cylinder head ASAP!!
FinalImpact;497329I find it VERY unlikely it ran out of oil. Bearings spin and the bottom end fries before the valves drop. Cylinder head not working properly IS LAME as is the oil pump. If it was repaired before said:So I bought this bike used from someone around November 2011. The bike had approximately 8,500 miles on it. The owner said he had it parked for a little over a year. he said he would give its maintenance and he was a friend of my father.(or at least we thought he was). Well he took for a ride and everything worked fine. I took it home and started riding it that afternoon. That same afternoon it gave me problems starting it up. At the time I didnt know why it was so but later I found it was the battery. A week later, a ticking/rattleling sound came up from the engine. We didn't know what it was so we did an oil change but it wouldnt go away. later the muffler began to backfire. We(my father and I) changed the spark plugs cause we thought it was that since it was backfiring. Well as soon as we did the spark plug change we turned it on and 30 sec after turning it on we heard something go loose from the inside. I tried to turn it on again but it wouldnt do anything. The engine got locked. Once i took it to the shop, they opened it up and it turns out one of the valves came loose and hit the piston leaving a scratch on it. they checked the cylinder and everything else was fine. Well they fixed it and replaced all the damaged parts with new ones. The mechanic told me he wanted to go deeper into the engine to see if anything else was wrong with it. once he checked it he said that it looked like if the engine had been overheated before. He said that the person who sold it to use lied to use because the bike showed no signs of proper maintenance. The tank is all rusted, they had it clean the injectors and this was part of the cause that the motorcycle struggles to turn on at times. Well i finally got it back and it ran good for 2 months. Until 2 weeks ago, i was going on the express way and i heard a rattleling sound. I thought i had gotten a flat but no, i had full control of the bike. I tried to accelerate but the bike wouldnt accelerate. I engaged the clutch and got off the express way with the speed I had. Once I stopped on the side of the rode, the motorcycle turned off cause i let go of the clutch. I turned it on again and i started to hear the same rattleling sound from the engine. it was the same sound it made the last time it broke down. I quickly turned it off. I took it to the shop again and yes, the valve had gone loose again and hit the piston, also scratching it and this time it hit the cylinder head(also scratching it). Once again, the mechanic said its the cylinder head, it wasn't any good and they had now way of knowing that the last time they fixed it so the only way you'll know is of course when it breaks down. And he also said things like that also happen when the bike is not taken well care of. I've talked to people who know the previous owner more than i do and they say that he never took well care of the bike. others say that the bike would always turn off on him and he would struggle alot with the bike. it makes me think that is the reason he decided to stop using it. He did help me pay off part of the service for fixing it last time and this time he says he cant anymore. I don't want any troubles with him so id rather just keep him out of this. he lost my trust and he is a huge liar for saying he kept it well cared. Well that is all the background i can give you on the bike.
I will attach pictures to show you what part of the cylinder head was scratched, they are not the actual pictures they are just for explaining purposes.
Before jumping on the R6 heads remember that the FZ6 frame is used integrally with the motor as part of the frame structure. Does the FZ6 head have threads related to the frame???

+1 I say just start with a new engine!
I wonder if the guides are worn out or improperly clearanced?
I pulled this piston out of a Mustang Cobra that dropped a valve at ~5600rpms....found the valve in the oil pan.
