99 f-150 4.6 cams

hi i am working on a 4.6 changing the head gaskets for a friend of mine and i was wondering if there is any way to keep the cams in the position that they are with something basic that i can find around a shop. i don't have time to order a cam holding tool cuz i need to get it done tomorrow. any suggestions would be greatly appreciated thank you.

There is not usually any way to keep them in time. I would go to a parts house that has a loan a tool program.
