at around what boost levels are guys pushing it to on stock valve springs or what level is it good to start looking at upgrading springs? Are there better boost cams available for the 1049? O ring the head to help with blown headgaskets? I know rpm range plays into all this but just curious as to what guys who have played this game do or recommend.
