Valve Springs from Airflow Research

I dont know where they have them made but damn they last. I just bought a new set for my 315CNC heads because i've put 3 hard seasons of racing/river use on them. My cam is fairly aggressive (under .700 lift mechanical roller) and i've run the motor to 7,500 rpm out of the hole quite often at the track.
Well after Darrin and I installed the new set i checked the old ones. Visually they hadn't lost any height and they were all within 10-20 pounds of the stock ones according to the spring tester. I guess i now have a slightly soft set of spare springs.
Anyways, if you're looking for decent springs these seem to last pretty long.

Wow...that's pretty cool. For a roller, 10-20# is nothing. If you have enough installed ht, you can shim that. Good springs are something to keep. I'd run 'em.
How much $ were the new ones??

Cyclone,i'm thinking about buying some AFR's also and that answers one of questions.Have you had any problems with them?

I ran those springs on my AFR CNC335s when I first got them and they worked very well.
