Engine 1995 Cobra, valve springs to work with E303 cam?

I thought FRPP had springs but they must be discontinued. Looking for something that require no machining. Thanks

Google Comp cams or Crane cams to find their support dept. Then once you have contacted them, ask for their recommendations.

E303 max lift is .311 on the lobe. The Cobra cam is .282. So a little extra lift and more duration over the stock cobra cam

Here's a good variety of spring kits for the GT40/GT40P. Unsure which would match up best with the e303

You need special springs for a 303? Stock should work fine (unless they are bad). I had to get custom springs for my 347. But I bet your engine doesn't turn 9,500 RPM.

Not sure if this is the right answer but I installed a Comp spring kit in my old LIghtning GT 40 heads. It had the springs and different valve locks to make the spring installed height as intended on intake and exh, as the valve lock grooves are at different heights due to the exh rotators. Should be still available. I had a 484 lift cam, no issues using stock rockers to 6200 rpm.
