1990 5.7L Silverado - Engine Image wanted

Please please please help me... I need an image of this engine so I can show what is missing on my truck... the Haynes manual wasn't quite clear, and i think I am missing two important plugs

I have a 95 Chevy K1500 (Silverado). I have a Haynes manual and looked at the engine compartment pictures and there are several components that I have that are not listed in ther picture for my model truck. Likewise, there are several components that it looks like I should have that I don't.

yea, its pretty shi**y

what two important plugs are you referring to? water passage plugs in the block? those definately have to be there or your coolant would pour everywhere. other than that, i dont know what other plugs there could be?
