Be very aware.....I've seen soooooo many problems with AFR heads right out of the box that I'd question everything about them. Check the valve stem seals at vacuum conditions like 84GT says. You may also need to pull the upper and make sure that you're not sucking oil past the intake gasket. Pull the heads off and have them gone through by a good shop. Check the valve guides and seats carefully. Also have the springs checked while the heads are apart.
