STD,
W330PS 76.00mm
W330P2 76.50
W330P4 77.00
W330P6 77.50
W330P8 78.00

You may can bore it one more size, a 78.50mm, but, you've got to pay attention to the thickness of the sleeve between the bore & that o ring groove. If that little piece of the edge of the o ring groove gets to thin it can break off after the head is on & engine running.
