Header gasket confusion

[DartVadar]

I dont really know if this is a problem or not but I though I would ask, especially since I am going to be starting up my new motor pretty soon and dont want a header leak to cause weird noises. The motor is a 360 with eddy heads and dougs headers.

I bought and installed these remflex gaskets http://catalog.remflex.com/MOPAR_Header_Exhaust_Manifold_Gasket_p/6009.htm

I used these gaskets last time without any issues

I noticed that the ones I have installed have a few extra holes than my heads have. They installed just fine, and I dont see any issues. But is there a difference between the two besides the holes and slightly different port size? Should I run em or change them out for the other ones?

those extra holes are for air injection. you can use either of them on the cylinder heads you have
