I didnt think it would be safe to do a LS2 418..... is it?

Me neither, but the only way I can come up with 418 ci is 4.03" bore and 4.100" stroke. Neither dimension is a good idea with a factory LS2 block.

If going with LS2 based engine then keep displacement to right around 400ci for FI. If going LS3 based engine then you can go upwards of the 4-teens area for FI. Both LS2 and LS3 based combo's are easily capable of making 700-800rwhp with FI. You don't need the few extra cubes to hit it either. I plan to make right around 800rwhp in my car and am only running a built 402 and TT's. The 16 extra cubes cannot hurt, so if you want them then do it with an LS3 based combo.

I think most people will agree that a 416 LS2 is not a good choice... you could probably do it, but chancy!!!!! I wouldnt go more than 403 or so on a LS2..... LS3 is a different story...
if your going to spend a bunch of money dont go cheap and then you will worry later on..... just an opinion,,,
