You have to have faith in a company you trust, and in the automotive industry trust is earned then comes faith. That faith could fall at anytime or be further strengthened by tests as such.
I don't know what you get from the test but what i get, is when i bolt the head back down the first time on a freshly decked block and head, it's gonna have a better seal with the cosworth gasket. I haven't replaced my personal head gasket, because i fight detonation with a vengeance.I have replaced head gaskets were detonation is clearly evident, on every single gasket ever made.
I'm looking for a company that makes a detonation resistant gasket made from aluminum, copper and titanium. or adamantium
