I am going to be buying a Comp Cams XE264HR cam, plus new lifters and a new timing chain. I was going to buy them from Summit - Comp cam XE264HR $246.00, Ford lifters $120.00, and a Comp timing chain $40.00, totaling approximately $406.00. Or I could buy the Comp Cams cam/lifter kit $445.00, and the Comp Cams timing chain $40.00, totaling approximately $485.00 Or I could buy the Comp Cams cam/lifter/timing chain/valve springs for $658.00 My question is - do I need to use the Comp lifters with the Comp cam? Ford lifters are $120 and the Comp lifters are around $200. Is the stuff in the kit any better than parts you can buy separately, or are they counting on people buying the kits to be sure everything works together?
