Welp I messed up, plain and simple. Got too excited I'd reckon. Taken from comps installation instructions Quote:
Step 5: Remove your new COMP CamsŪ camshaft from its packaging. Inspect all lobes and the distributor gear, making sure the camshaft was not damaged in shipment. Next, compare the stamped numbers on the end of the cam with the spec card to make sure this is the correct cam. It is a good idea at this point to lightly wire brush the distributor gear with mineral spirits or an equivalent solvent. Remember, during the installation process, the cleaner you keep your new components, the better chance you have of avoiding failure. Using COMP CamsŪ Assembly Lube (part #103) supplied with your cam, coat all lobes and distributor gear. It is important to coat the lobes completely, yet not excessively. This same rule applies to the distributor gear and fuel pump lobe. Coat the cam bearing journals with conventional SAE 30 or 40 wt. oil. Note: We do not recommend the use of synthetic oils with our cam and lifter packages during break-in.

I would be concerned they didn't hone the cam bearings to size.
i would be concerned if they did. these bearings are not meant to be honed. camshaft bore accuracy is a very common problem with BB mopars. in my experience it's unusual to NOT have to scrape bearings to correct a tight cam. normally i will install the bearings one at a time after the first two checking cam fitment after each one. if there is binding it will leave a shiny mark at the high spot that can be scraped with a bearing scraper or by carefully dragging a new razor blade backwards across it. as mentioned only oil is really necessary for installation as the engine should be primed before starting anyhow.
