As long as "they" didn't assemble anything I imagine you are ok, but inspect work from everyone. I had CP make me a custom set of pistons and the first set that came back had a 3v exhaust valve relief instead of 4v intake reliefs. Great company, used multiple times and they still made a mistake. To their credit they had me the correct piston within a week but people make mistakes.
Thanks guys I'm hoping everything is correct so that rebuild can finally start. Excited but not considering the season will pretty much be over by the time everything's back together. Guess I'll just take it slow.
