I use Bosh Distance in my Jeep Grand Cherokee Hemi and AMS oil filters on my Grand Prix GTP. In my Comanche I will probably use the Bosh Distance. I have been very happy with them.
So if I understand correctly what was the original cam in our engine? Why do I have to switch to a different oil? Is there a Castrol product out there I can use with this engine? Thanks for the clarification on the cams.

Wix and Napa Gold are excellent and available just about everywhere FWIW.
what the hell is a bosh and ams?
Huh? He says they are too long but can't measure the preload? How did he determine they are too long? Besides that pushing the lifter down by bolting something to the head isn't how preload is measured.The owner called me today and he said the pushrods were about .030 too long, to no suprise to me and that the same problem I had with the crooked rockers came back. He said he couldn't determine preload since he could not bolt anything on the head that would push the lifter down enough.
Being that it is a modified engine push rod length may need to change. Cam base circle size, deck height changes, valve changes, lifter changes, etc can effect preload and correct pushrod length.
