I did some askin around when I was beefing up the motor for my lil car, & was reccomended the GM EOM stuff many times from people that build monster motors with serious cams, it has a very high Zinc content for just this purpose.
In that particular market poor cam surface quality is an issue when breaking in new parts, many of em swear by it and when I broke in my last rebuild it worked great.
sed it as assembly lube, then poured the rest of the quart in the engine & topped it off with my favorite oil.

1956 GMC 370 dump " 'Tater "
1970 VW Volksrod "the Black Bomber"
2007 Chevy Avalanche
2020 Jeep Cherokee Trailhawk,
2005 Harley Davidson FLHTCUI

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
