Do you guys think i need to pull the head? i’d definitely like to avoid that if i could. I’ll probably end up replacing all the valve springs if two simultaneously broke to be safe.

also any tips on reassembling? i marked the chain and sprocket with a marker and have the lock tool from my Ims kit. it’s a variocam 3 chain motor
These are interference engines.

If you have broken valve springs then there is a very good chance that the pistons have contacted those valves.
So the valve stems on those valves could be bent or there could be damage to the valve guides, and or damage to the valve seats.
Or other damage.

The only way you are going to know if there is damage is to remove the head and have it checked out by a good machine shop.

You may have dodged a bullet and can save that engine.
Pull the head and have a automotive machine shop examine the head and check the specs.
That is the prudent thing to do.
Anything else would be foolish in my opinion.
