I just finished installing this head along with the CA625+ studs and the SS exhaust manifold stud kit. With the additional boost from my turbo and other mods done to the truck the head gasket just didn't stand a chance. Installation of these parts were straightforward and once installed has worked flawlessly. Already put a couple thousand miles on it with zero issues. I now have consistent engine and exhaust temps and my exhaust manifold is all snug and secure. Turbo spools up sooner now with the added airflow from the larger valves and I've actually seen an increase in my fuel economy in the 10-20% range. I'm loving these parts!
