proibe Phil 3 choices, the rockers look like new, send them back to Dove and see if they will stand behind their product, I see no wear problem on the side of the bodies that the side clearance was not enough. These rockers are going to move around to center on the rocker adjuster is possible. They are going to move around to try and center on the center of the valve stem.
3 choices
send back to dove, POLISH shafts, make sure you have good oiling to the heads. and try again with Dove
#2 remove the rockers and install stock steel rockers on the shafts you have and don't worry about the last 2-3 hp you might loose between the different.
#3 Call Brent B and buy a set of Ersons from him, KCR, E-Bay, or Doug. Who every gives the best price. Sell the doves or hang them on the wall.
If you go with line 1 or 2, take the time and make sure that every thing is flush and square on the heads.
Ersons are a bolt on system and may only need a little machine work on the end mounts, depending on what you have to hold the heads to the block. Head bolts no problem, head studs and nuts like ARP, trim a little on the bases of the rocker assembly for a flush fit. You have $40+k in the car what is another $725.00.
Happy holidays Rick
