If I changed from 317 heads to 243 and threw in a say 228r cam or something would I be able to use the valve springs that come with a TSP cam or would i need something different?

I am running ported 243's on my LQ9 currently. The valvesprings will be the same, which would be at least beehives offered by TSP for the cam you are looking at.

Are you running a cam? and what length pushrods are you using? i think 7.400" is what i would need but not sure, and do you know if just a beehive cam package would work on a lq9?

pac 1218 springs ,706 heads work great on lq4's , to bump up compression , they make great power , your 317 flow better but , the 706's will make more power due to compression increase

I had the old grind 228r cam (.588 lift) in an otherwise stock LQ9 with 317 heads and PAC 1218 beehive springs. I believe I was using 7.400 pushrods with that setup. After a good tune it was a really nice all around cam for a 6.0. Currently have a forged 370 with 243's that were slightly milled and a cam motion 227/232 cam with around 5.900 lift running 7.375" pushrods. You are best off getting an adjustable pushrod and measuring to get the right length for your specific set up.
