It's a shame, but Megacycle has discontinued the NS billet cams for the XV series.   These were forged whole, then ground to whatever profile the customer wanted.   I asked if they would sell me unground billets even, but was told I would need to order at least twenty sets for them to do a run, and I would get charged at finished cam prices.   So, somewhere down the line, I'll be modifying cam journals and heads to run a different bearing.
