Yes, it will damage both cards in the long run. Find a smaller 50x50mm heatsink, also swap the cards.

PS. Increase the RAM to at least 64MiB.

And/or look for a different motherboard. The BabyAT form factor always has challenges with some long cards, but a lot of boards have the CPU lower down, impacting a couple of ISA slots and leaving one or two PCI slots free for longer cards.

There are also shorter S3 Virge cards - in particular cards by Diamond and ELSA are frequently not much longer than the slot itself. I see the Diamond Stealth3D 3000 pop up quite a lot. It also has very good analog image quality (commonly poor on S3-based cards)

To max 64MiB. This board has an i430VX chipset and can only cache 64MB. If it's just about playing games, no game that would run well on this setup would need more than 64MB.

Yes, I completely forgot. I'm just thinking about the K6-2.

What's wrong with swapping the 2 cards?
The vga is shorter
