Help me with a cyl-head gasket mystery

Here in the USA I buy Felpro but that is my person preference. Never had a head gasket fail until I used an off brand that is no longer in business. They were cheap and I got to do it twice. I have no idea who Corteco is. Reinz used to be Victor Reinz and they used to be good but FelPro has the market around here. It does look like many people use Corteco and from reading the posts they have bought or was bought by ROL. ROL is the company that I bought my bad gaskets from but that would have been many years back.
