which valve springs---- i have 3 choices
I have stockers for the 5.3, then i have the Yellow springs, and i have Katech ls7 springs...
now i know this isnt the right way to determine,but squeezing the stockers by hand and the yellow springs,theres a slight diff,but these katech springs a much more stiff,they all appear to be the same height,i just dont want to mess up my zo6 cam that i just installed...
this will be for turbo application,i will get the link to katech springs and post a pic..soon
