At one time, UNported heads were worth more than ported ones, because you couldnt run ported heads in stock eliminator, and heads that had been ground on were much more common.
Since mopar came out with the new version of the iron maxwedge heads, value has dropped somewhat.
I have two sets of the 286 heads, one on my real 426 max, and another set that were professionally ported more than a few years ago. I had IMM go thru them, new valve job, valves,guides, springs and retainers and keepers.
I doubt i would have spent that money on stock castings.
And yes, ive got a set of victors too.
If i had to do it again, there would be a set of tf 270s in my cart.
