I've never used any goop at all on my cars and never had a problem. Why use
goop? Just curious.
It isn't a 1098 gasket is it? Smaller chamber size that is a different
shape. It will fit close enough that you will not notice the mis-match.
You shouldn't have any gasket overlapping the chamber. The 1275 A+ heads
have fewer water holes than the 1098 heads in my store so there are 3 spare
holes in a 1098 gasket if you used it on my 1275 with about 1-2mm overhang
into the cylinder.

Something

Remove the studs and chamfer a little from the tops of the bolt holes with a
45 degree coutersinking tool in an electric drill. Just removing the
topmost thread should ensure that if the stud has previously pulled up a
ridge of material, it should no longer pose a problem. Clean up both
surfaces and lay the head down on the block with just a couple of studs to
locate it. Shine a torch through from the other side to show up any large
discrepancy since you know your head was OK. Using a straight edge ruler
isn't 'always' a guarantee as you aren't sure the straight edge is actually
straight!>

Could be a crack between the water jacket and the roof of the centre exhaust
port. For the cost, I would at least try another head, although they are
possibly more expensive over on your side of the water. £5 over here.
Good luck
