You know, I thought about that, but thought the cam lobe would spit the lifter out of the bore when the engine started. Nothing to hold it down. Have you done this before?
I have, but I removed the lifter each time for insurance. It's a little tough, but you can get them out. I don't really think the engine would throw the lifter up that far.....at idle anyway, but still, I would hate to have it do it while running. I think they'll fit down those holes in the lifter valley. That would suck. If it's a pretty fresh build, they should come out easy.
