Sounds good in theory, but we dont know what he has under the bonnet, he may have put in an LT1 or LT4, or he may not be refering to the 87... But if he is, at least he is being cautious!! 
You can wash an LT1 anyway, i do it all the time and im yet to have an issue. Do it with the engine running, and be sensible about where youre hosing.
