Default Pics:What do you think about this scratch on a freshly rebuilt gsr?



Picked up my head from the machine shop, and the machinist wasn't there so I didn't notice the scratch or get to go into detail with him but I definitely will Monday.
but what do you guys think? Also do you think this head was resrurfaced past the service limt just based on the pic?
It's still above the two square tabs but it looks really thin to me.
What do you guys think good enough for THICK mls hg?

The scratch is not in a critical area, so it likely will not be any problem at all.

The square deck casting recess is typically .040" +/- .002" deep on a stock virgin head casting. So measure your depth and you will have a good idea how much has been machined off the head surface. It is customary to add this missing value to the head gasket thickness to maintain proper belt tension, camshaft-to-crankshaft phasing, and compression values.
