74.5mm headgasket to 74mm pistons

[msg1]

So my old gasket went MIA on me. I am seeing a small water leak at the back of the engine right at the head gasket. I have been hunting a replacement 1.6mm headgasket but to no avail. I have sourced a 1.5mm Cometic. However, my Wiseco pistons are 74mm and the Cometic gasket says: 'for up to 74.5mm'...will this work together?...i know it's a pretty newb question.

Have not started stripping down yet so I am not sure what was the bore size on the old gasket but contacted the seller and concluded it was a 75mm.
