I took some time and read through this thread a bit. Did we build this motor? If so, it had to be a long time ago, I have not built flat tappet motors for some time. What lifters were used? There is a big difference in them. I think I too would go ahead and run it in paying attantion to lift now and later.

For your Information: Here is one example of a camshaft regrinding Company that Parkerizes it's camshafts It's website is:
http://www.blakesreman.com/remanufactured-camshafts/
Here is a quote from the Web Page explaining the Parkerizing process.
Quote:
> Pakerizing Process for Rebuilt Camshafts
>
> The founder of Blake’s Remanufacturing, Robert Blake, discovered long ago that Parkerizing rebuilt camshafts and lifters helped them hold oil during the start-up process, thus making a smooth clean start-up that was less hard on the engine. Parkerizing is a three bath process that applies a non metallic absorptive coating to the outside surface of the rebuilt camshaft and lifters. This permits rapid break-in without scuffing the cam lobes. It also helps prevent against corrosion for the rebuilt camshafts and lifters in humid climates, and those stored for extended periods of time.
>
> The mains on the remanufactured camshafts are taped and not parkerized. When the remanufactured camshafts have completed Parkerizing we spray them with a dry graphite film lubricant, this also protects against corrosion and acts as a lubricant to prevent scuffing, scoring and seizing. Both processes will give the reman camshafts a Dark Charcoal Color. It is important once the reman camshaft has been parkerized to not remove the graphite spray or Parkerizing. We stand by this process 100% and believe it to be the most effective way to protect our reman camshafts for long durability. If for any reason you don’t want Parkerizing or graphite spray applied to your remanufactured camshaft please let us know ahead of time and we can accommodate the request.
Best Regards
