I would think if there is a problem with Comp Cams cam journals, they would have a recall on them. Same if the dimensions were incorrect.
Sometimes, when the surface is not real smooth it actually holds & retains the oil for better lubrication. Like having knurled valve guides, knurled pistons.
Ian, after you dyno test your new engine with the new grind, that would be a better way to advertise it's potential, most important, how it drives,, does the boost come in quick, mileage etc. Real driving impressions. A dyno is a good tool for adjusting, & tuning an engine, but does not compare to actual driving & give first hand knowledge of your experience. And if the results were good, then maybe Tlowe would stock it.
