Why do you guys need an upgraded valve springs for JUN cams? Valve springs are excluded from the set, apart from other motors Cam where they're included. It means that OEM valve springs will be capable to hold these cams.
I bought 288 JUN cams and I did asked them personaly- do I need any valve springs upgrade or other modification for these cams? For what I've got reply - No you don't
