I polished mine few years ago, lot of elbow grease and a few power tools.
It was already badly polished before and the clear coat turned yellowish so I had to remove it all before, it made the job much harder.

Thank you all, I guess it's time to take some measurements and decide how to proceed.

There's also a couple of dents which makes me worry.

I have another engine with lower mileage I was not willing to use cause painted blue, i think to remove its head and compare

Don't look right to me, maybe there is a reason you got it for free! 

I guess you're right

Hi guys, greetings from Italy.

I'm refurbishing a GSX-R 1100 H engine I got for free years ago. The previous owner told me it was used for track days and tuned up a bit, but it looks completely stock to me.

I have a doubt anyway: the head plain is very low around cylinder 4-intake side (at the same level of head cooling fin) while the other side is higher, about 1,5mm more. Is it normal or is it the result of a bad machining work?

 

Low side, same level of fin

 

Opposite side, much higher

Thank you
