they would work just fine. how many R's are you looking at turning. pretty large investment for almost not if you arnt over 4k. 60lbs springs and stock everything elso work fine with a 4gsk kit. the valve can pull through the stock keepers at high rpms and it would make matters worse if the spring tension was higher on top of that. all depends on what you need. the cam/pushrods/rockers open the valve. the springs return then to closed. generally higher tension springs will close the valve faster which is what is needed in the higher rpms so you dont float valves.
