I'm thinking about getting water meth injection (snows stage three), delivery valves, and 4k valve springs after I get my tranny built does anyone have a truck with any of this set up? I know the valve springs are common with 12 valves but I haven't heard a lot about water meth on 12 valves. Does anyone have any input??

 

alot of people run meth. it works great. i would add studs to ur list also.
