i have a mostly stock 01 yukon 5.3 with exhaust and k&n intake. im about to get a custom tune(probably bb) and drop in a monster transmission to replace the slipping stocker 4l60e but before i can do this i have a valve tapping that must be fixed. the problem i'm having is i know i need to replace my valve springs but im not sure of the size of the springs. im buying a valvetrain kit with pushrods, springs,etc. i think i need a spring with a 1.72" installed height but im not sure. anyone have an idea i can really use some help on this.
