Oil for Roller Cam

I am in the final stages of getting ready to start my 340 after i
installed a Comp Street roller.I am waiting on a set of pushrods,which
will be here Tuesday. I would like some opinions on the oil i should use.
I was using 10-40 Pennzoil with Hughes additive, when i had a solid
flat tappet. The old cam and lifters looked good when i took them out.
Thanks for your advice.
