Valvesprings don't last 200k on cammed motors like the stockers do... they are a maintenance item. 
Replacing 1 Valve spring
Replacing 1 Valve spring Well one broke today after my tranny swap. There is only one broke bought the motor used so not 100% sure what brand they are say I get on that is good for the lift of the 306 does it matter if it is a different brand then the others? will this hurt anything

I'd be uneasy about replacing just one spring unless I knew exactly what brand that and the other 15 are. Like speed_demon said, the other 15 could be on their way out, too.
You don't have to spend big bucks to get a good set of springs. I picked up Patriot Gold double springs with seats, seals, locks, and retainers for around $260, and they're good for a .650" lift.

You cannot match the proper open and closed pressures and install height without knowing what the rest of the springs are.
A spring for your modest setup would be relatively cheap - just get a full kit, change them all, and have piece of mind that the job was done right

Thunderracing tends to have alot of 10% off sales and they have patriots. The 8401's are what i have so im sure they would work well for you too. I think they were like 230$ after the 10% off.
The 8501's im sure are overkill for your application.
If your install height is 1.750 then the 8401's should be good. Thats if you want patriots. If you want the beehives then the Pacs that everyone else gets would be fine im sure.

Hopefully it's nothing more than the brand of spring you used.
