Just a thought, I've got a new set of roller lifters for my LT1 project. If I recall they were Comps. They've been sitting in oil waiting for me. Point is, it looks like I've got 75% of my parts for the LS1 eng rebuild and if I could use those it'd be another item off my check list. I know they look the same, I can only imagine that the bore size is different.

The height of them might be different as well as the preload meaning you'd need difference pushrods. I'm honestly not sure. As far as i know the only interchangeable parts from lt1/ls1 are the crank bearings.
