Hey, just wondering how much lift the stock valve springs on the AFR 185 heads are good to? I think that DSS told me they were good to a .550 or .560 lift, but I forget. I'm just curious b/c I'm running the crane 2031 cam, which I think has a .524 lift or something, so I should be okay, but I just want to verify.

yeah, I agree. That's what I am doing on my 165's. Some may suggest upgrading in advance, but I think you will be fine.:joy:
