Magnum heads worth the effort?

you reminded me of the seat, so 600. I bought push rods, 99 bucks. Most aftermarket cams/lifters have oil through lifters. total 699.
So cool $699 and I guess we should at this point mentioned since it took you hours? Possibly days of grinding? I know you like to talk about flow so just in your wildest best guesstimate what do you think those are flowing?...
