Thank you double R & yeah I saw that descrip on the unfinished ports but I ASSuME'd that they were ready to run as is but that a person could take them out much further if desired. so maybe they would not be in a good shape/form to run as is. Matt 20% is enticing & I have a new set of Manley 2.14/1.81's on the shelf & I would use stock BB retainers & mild springs (have them too). I always go way too conservative on cams which hurts me but just me I like a smooth idle & I'd do the valve job & I definately ain't a pro porter but I can do some slight/moderate clean up/port matching. I'm assuming the Victors are a better head and do not require the offsett intake rocker assys. Thank you!
