Flathead v8 gasket question

[Garageguy]

I have a question about flathead gaskets: could I use the copper ones in the picture as a replacement for the one below? I know that the centre holes ie triangle, round and square are different. Would this cause a problem ie water flow, or would it have not much of an effect?

Yes you can use the copper ones. If you have aluminum heads, I'd recommend the composite ones from Best Gaskets. They call them GraphTite gaskets.

Thanks, just using iron heads. So there will be no problem with water flow?
