5.9 & a solid roller

Yup. Just the Magnum block.
Not the heads. I have the W series @ the ready.
besides the shaft oiling problems, I think it will be pretty straight forward.
these t&d rockers look like they oil from pushrod. Although they are expensive. (I already had a decent set of rockers and i'm cheap, which is why I modified my cheapo heads.)
