If you are not pulling the heads, you can't swap the lifters. If you are pulling the heads, I wouldn't say changing lifters is necessary, although I would definitely change the lifter trays. They are only about $8 each and you need 4.

I will do it if its really necessary. But then the head is off, and you know what that means..."might as well" upgrade. Iv seen people in searches saying replace..its cheap insurance..like bww3588 did(no offense and not to single you out) but I havent really seen any technical reasons. Wear patterns on the roller tip? they get weak after xxxxx amount of miles? The lifter could collapse because of xxxxx amount of miles and with the new higher lift cam there is more stress? Just wondering

Oh im definitely changing to hardened pushrods, dual patriot extreme, ti retainers blah blah..I guess if I change lifters I wont have to worry about using dowels or magnets to keep the lifters up. ha. My motor is on the stand so I have easy access. If I put new lifters in what head gaskets and head bolts should I go with. Replacement GM or get ARP.
