Biggest mistake ever- lunati cams

I built a nice street 360 a little over a year ago using Speedmaster assembled heads, and a Summit 1789 (Crane) cam. The springs that came with the heads were way to much for the cam. I had to do some research, checking of specs to source the best springs for the cam, the retainers and required shims to set them up correctly. It is all on the one assembling.

But I agree, the times I tried contacting Lunati was nothing but frustration.
