Oil puddeling on intake manifold .Factory 273 4bbl duel exhaust

I too am getting oil puddling on my LD4B intake (which started about a week ago). I understand I must remove and clean the bolts. Do I need to clean the bolt holes? If so, how & with what? After I apply the sealant do I immediately re-install the bolts or wait for the sealant to set up for some time? Once the bolts are re-installed how long should I wait to drive the car?
