Ok , I have searched for all this on here but, I must suck at searching. I have a 11 rt 5.7 vvt non mds motor installing a 6.4 non mds motor cam . my question is this i bought a kit the guy told me he got from mmx attached will be the pictures of what i got . My question is do these parts look correct and my real concern is the valve springs hhp shows it takes 1515 springs not 1511 springs or am i misunderstanding what they are saying. Also i am looking for upgraded pushrods are manley 26640 pushrods correct. Thanks for any and all help this is my first build .
