not installed yet BUT....
I bought one of these not to long ago due to having to do a cheap emergency repair back in october then as i planned 6 months later I had to do it again. This time i got the head surfaced new gasket, arp studs. 3 months down the road I am already doing it again. I am honestly hoping it was a Defective gasket, so here I am again doing it for a 3 rd time in less than a year. Hopefully this will be the last time for another 300k miles or more.
