Unique 318 Engine Balance Questions

Ok guys I've officially confused myself with my build and need to make certain my engine balance is correct for my little turbo 318 before I install it. What I have so far is this:

Magnum 318 with stock rotating assembly, no changes from factory
904 neutral balance converter
Neutral balance flexplate
LA style pro street damper for internal balanced engines

I went with LA timing cover because I didn't want to mess with magnum accessories or fan and I had to put the alternator on the drivers side to make way for the turbo. I've read that magnum rods are 10 grams lighter than LA rods. Could this alter engine balance? Engine won't likely rev over 5500
