Look in the older posts, there was a lot of work being done to the 630/631 about 15-20 years ago.
There was a surplus spring from a machine gun from Princess Auto that people were using.
The best thing I've found for these was the full power spring, it brings it up to about 650fps (if you have your PAL) which is great for this style gun.

If this is going like your last post, please be ready to post details and pictures of your modifications. Any made up stats will get this post deleted.

I've tested a couple and found the Cdn detuned Slavia 630 often shoots 7.9 grain pellets at around 440-450fps. I tested two full power versions that shot 650-660fps. The full power mainspring has a few more coils and possibly a thicker wire. Unfortunately it's not easy to find the springs anymore. Same with the piston seals.

In May of this year I purchased a full power spring from Woody(username) on this forum. My Non-PAL 630 went from 502FPS avg with Exact Express 7.87 gr to 627 FPS. H&N HP7.1 gr did 662 FPS
