I'm running a 350 in my '81 Camaro, I have a Performer RPM intake and camshaft, and a set of headman headers. I can't afford a set of heads, so I am going to be using the stock heads. So my question is, what kind of valve springs should I put on, or will a set of camelback heads with stock spring be fine?

 

the Edelbrock valve springs that they sell FOR the RPM camshaft should be the best since they are designed for it. But even if you use the stock camelhumps i would buy new springs. The stock ones will handle the lift if I'm not mistaken, but you can replace them for relatively little cash so it's worth it. check ebay.
