PAC 1218s and kinda wish I'd have just gone LS6 springs... Not that there's anything wrong with the PAC, but I am running a fairly mild cam and the 1218s are a little noisier than they need to be. (I am using the factory net-lash system, 7.400" pushrods and the cam had the same base circle as stock.)
