Cam re-grind

Mark I think it's perfect for the rest of your combo. Your engine will not have adjustable rocker arms unless someone installed them. The only adjustable small block Mopar's I know of are the old 273 commando's and the 340 T/A engines.

Did they tell you the stock valve springs are not up to snuff for that much cam? You also need to check for valve spring retainer to valve guide interference with that much lift. To be honest I'll be surprised if there's not interference with that much lift. I've checked a few sets of stock heads and found .500 lift at the valve was the absolute maximum any heads would take before you have to have a machine shop cut the guides down and install PC or Teflon seals.
