its always recommended to upgrade the valve springs with any cam swap
Recommended but not required. Ive installed a lot of aftermarket higher lift cams with stock valve trains with no problems. My bro had a problem with his factory pushrods after he upgraded his springs, bent 2 in the first 10 minutes of running the car.
sounds like your bro was too stupid to upgrade his pushrods which is required when running stiffer springs.
He was inexperienced, hes not a car guy. I didnt do the install, and found out later about it. Of course he was too cheap to get a 90* fitting for his fuel line and started a fire under the hood . I've always run 1 piece hardened pushrods.

if you have to use one of the two letter cams I'd go with the B303 + 1.7 RR
What the hell are you planning on doing with a 529 lift? Do you know what your saying?
