Exhaust valve problem

[luke]

I have been grinding the valves in on some heads i have and all was going well till the very last valve. I have put up a picture for someone who knows more than me to look at, one is the inlet, one is the exhaust, as you can see the exhaust valve has a far bigger contact area with the seat, is it worn? The guides dont feel too worn, do you think this will work okay? The valve in question was not seated well before i ground it in and the exhaust port was full of black nastiness,
cheers, Luke.

if you have a manual it will tell u seat widths but wider seat on the exhaust ant a bad thing(on a stocker)as it helps heat transfer and will stop valve burning out
