Default 75.5mm Headgasket with a 75mm bore? Does it matter? (cometic MLS)

I found a cheap cometic MLS 75.5mm headgasket and Im in a crunch for a gasket and saving money is good

but can I use a 75.5mm gasket when my bore is still the standard 75mm?

Thanks

I've never done it but my instincts say it's going to leak. Get a Napa gasket, like $30 and I can say from personal experience I have boosted on them and never had a problem.

Its only 1/2 a milimeter though, I figured it would be just fine

It's fine, it won't hurt anything and you're no more likely to blow it than if you had a 75.5mm bore. What motor has a 75mm bore?

I don't know why most people don't understand this.

It's not a .5mm difference! It's .25mm - that's like a human hair.
