<VV> Loud noise when hot

[Ron]

An anomaly that I noticed last night is that the head "lands" where the head 
gasket seats are grooves and are at least half as deep as the thickness of 
the seal rings.  I assume that it's something that happened over the last 
forty years but it doesn't look good.  What causes that?  I'm inclined to 
double gasket and reinstall it.  Any comments on that?

Thanks,
RonH
