When I questioned PAC, although they didn't recommend it, they said most were more than likely just throwing the 1409Xs in the head without a cup. Now fast forward to having my break in rockers not work, I needed a solution for a light spring for break-in. I ran across a direct drop in that works perfectly with the cup and the retainer from the 1409X... they're factory beehive Dodge Viper springs that will show about 85lbs at 1.800 (closed). Hope this helps someone in the future.

Have you considered making power runs with the "Viper" springs? I wouldn't be surprised if they are pretty good for your combination.
See you at the races,
