mopar performance red valve springs with stock 340 camshaft

there have to be quality springs made now , can't all be crap . I'm goingto rebuild my 1970 340 that has been sitting for 12 years engne has maybe 15,000 miles Ill have the springs checked if they are not close to perfect new springs it is , not like they are 100.00 a spring am replacing the cam as well with a comp cam 20-227-4 i think , nothing to radical.
Good luck with your 340 even stock they pull hard
