Yeah, like what was said, 7.4 hardened pushrods must be done. Your cam is a good candidate for FI. The 115 LSA will keep it more civilized for DD. Those PRC springs are probably some of the best out there, as well as those Ti retainers. You are definitely building it with the right equipement to go FI. The stock lifter will be fine. Those springs are a very high performance spring. Since they are a lot stiffer than others (Comp 918's), you will need to be careful with them. They will need a proper warm up period everytime you cold start it. You really shouldn't start it up, then rap it up to 4k RPMs...you should keep the RPMs pretty low (~2k-2.5k) until normal operating temps have occurred. Your valvetrain will be noticeably louder, only because of the high rate of spring---you will have a louder clickity-clickity from the springs. Nothing to worry about, it is just how they sound. You will be very happy with what you have purchased...
