Wanting to run the summit e303+ cam with 1.6 rockers, the cam is .550/.540 lift and I’m wondering what valve springs would be the best if anyone had links to any.

What cylinder heads are you running?

Have you called Summit to see what they would recommend with your application?

Valve springs must have enough pressure to prevent the valve from "flattening" or losing its return force, especially with such high lift. For .550"/.540" lift, you will need springs with moderate to high return pressure.
