Stockish 340 upgrades, cam needed

I told him yesterday that the non CNC heads I feel would be a better choice as I think they will work better down low. I told him he will likely loose some low end grunt with the CNC heads. Then I told him that the new cams are light years ahead of the old Comp 270/470 cam in there now. He agreed to a cam change. That’s why I posted this thread. I will use the CNC heads. Kim
