This statement is grossly inaccurate; a side by side comparison shows a noticable difference in the fire ring construction with the advantage going to the Victor-Reinz which makes them for GM. So GM and Victor are the same, and Felpro are their own.
Grossly inaccurate? According to you I'm 66.6% right. What would slightly inaccurate be?
A 100% accurate statement would be that I've blown all of them up and it would be grossly inaccurate to say that the gasket was at fault.
