If I was going to go with a Comp Cam I might pick up the hydraulic lifters some where else and avoid the Comp lifters all together.
I once used a set of sealed power lifters on a comp cam and had no problem. Adam says theirs only 2 places making lifters. Don't know about that but if it's true the Comp lifters must not be sealed power made.
If you read the top posts by me I was amazed by the solid cams that Comp offers over my hydraulic Mopar cam. The Comp Cam XS268S would gain me 7 more HP and 21lbs of TQ!
