Are thick head gaskets legal for compression correction?

[gran racing]

What would make that a bad thing instill of milling the head?

[Dano77]

My AS car had the heads milled too thin by "accident" we used 350 gaskets on the 305 to lower the limit, same compressed thickness different bore. The fire ring was .250 larger on the 350. Brought it from 11.0-1 down to a paltry 10.3 ish. got below the limit though.

Not saying its right, just that its an option. There must be a larger bore gasket for a VW out there with the same block?????
