And if so, what'd you dyno?

I had considered the TR224, but there's a place that sells dual springs that don't require machining of the valve spring seat area (the springs drop right in, with West Coast Cylinder Heads spring seats), and they carry MMS cams. Dual springs would be nice, and I might as well buy everything from one place, if the cams are similar.

Is there much difference between the TR and MMS 224? Lift and duration at 0.050" is about the same, and advertised duration is too. I'm not saying they are identical or anything, but they appear to be very comparable from the published specs. Haven't heard as much about the MMS224, though, versus the TR224.

The springs are Rev 1116 springs, BTW. Anyone heard good or bad about them?

Thanks,
Miles
