I still would not use pro parts for a head gasket.
Maybe I'm biased; tell me though are they exactly the same as OEM? Or just good enough? Who makes them? Or are they designed and manufactured in house?
Of course there are some parts which you can get away with using cheaper aftermarket, like I always say though OEM fitment genuine parts fit better, work better and last longer
I'm not up for testing gasket quality on my cars head gasket by saving a couple of dollars but if others have used them and they've lasted, maybe those gaskets were made on a Wednesday but, there's just a good feeling I get when I stick to genuine parts used in critical components
