Cylinder ?'s on 05 M6?

[TB1000]

Hey guys,
I am currently putting a new top end in my 05 M6. I noticed when I got the cylinder off that there was a small chip in the exhaust port. I would say that its about 1/16 of an inch square. I was just wondering if any one had any ideas about wheather I should re-nickaseal it or if it will be all right? I live in colorado and was also wonder about how much it should cost.
Thanks

Any damage like this from the bottom of the lowest port up should be addressed. Especially if it is around a port. It will flake and cause BIG problems. Get it replated or get a replacement cylinder. Replating is $195-225.00 from most places.
