Please could I ask your opinion of the scratch to my 1275cc engine block surface as per image below ? you can't really feel it if you run your nail over it but just wanted to check if this will cause an issues ? I'm due to give the block surface a final clean  prior to head gasket install and was wondering if I go over it with some fine wet and dry ?

I don't think that will cause you any issue at all.

Do not ever be tempted to sand the block or head surfaces.Steve..

Thanks for the reply, surely you need to clean a head and block surface before installing a head gasket ? I'm talking about a extra fine wet and dry paper ( 2000)  used on the surface not a grit sandpaper ?

i agree i would not be using any sort of abrasive, cleaning it is one thing but dont sand with any type of Grit

It's on the other side of the fire rings and far enough away from the coolant port not to be an issue :)

On the second picture is that pitting on the fire ring surface on the narrow part between the bores ?

If so I`d be getting the block face surfaced.

I wouldn`t worry about the scratch

If you are concerned with deck blemishes, use some spray on Hylomar on the gasket.
