The deal is guys that I have thease heads, I do not have 915 452.... so I want to know how much potential thease have and what I can do at home to improve them, since I have a valve grinder and they need nothing but a quick VJ to run, probably would actually run fine as is but there is some very fine pitting on the seats. The guy was running them in a firewood hauling truck for years on 87 octane and the seats are not sinking, hardened seats are over rated on a mopar.

11.90 is good to me, no cage required and no $1000 set of heads.
