They are variable in their weight...

I have two young snakes. One male that is a mid 07, and he is around 450g, and I have a late 07 female that is very small, she is just 160g.

I recieved three males, all late 06's, March of last year... all 3 were 350-400g.

Now those 3 males are 1000g, 1100g, and 1600g. The difference in the 1000g, and the 1600g is striking!

Sounds like yours are doing good, and having a good scale is criticial. If you ever need to see your vet, having feeding schedules and weights is great information to be armed with.
