Crane, comp or Patriot performance has their own dual spring?
I would hope one of these could last 30k miles before the need of new ones

For those of you running pretty hot set-ups I would recommend getting an on the head spring tester. Note the pressure of the spring new and periodically check the pressure. When you have a 15% or more drop in seat pressure time to change. The tester runs around $100.

Be VERY careful when going to springs larger than 1.43 OD, they require the spring pocket to be cut very close to the exhaust port. If the head has ever been hot, the risk of a failure is greatly increased. I would definitely Rockwell test the heads before machining for any of the big duals. The Patriot and Comps are the best out for such a big lift cam now that we've found.
