I was just curious, I'm glad it's worked for you. I've seen plenty of corners and things broken off of cast iron parts, maybe the intakes aren't as susceptible to that as other cast iron parts if drop checked.
I ship five-six packages every day..every kind of part you can imagine.
I know what's fragile and I know what's bullet proof. Trust me when I tell you, an iron big block intake manifold is utterly impervious to any perils the USPS can impose on it.
