Buy cam and springs from blykins, he has history of what works. Return the can you bought unless it is one he has used. Cam is brain of engine in addition to most demanding service. You can really screw up an engine fast with to light or to heavy spring. Normal joe working on engine has little chance of optimium combo coupled with crappy aftermarket parts which come bad from the manufacturer, just buy a package deal from him.
