double valve springs

[69 Valiant Kid]

when i had my heads cleaned they took the valves and springs out, and did not mark them. i take it they dont differ from intake to exhaust valve? i know new cars do. any help is appreciated.

thanks again, kurt

Shouldn't be a difference.

If the heads had rotators on them, trash them.

Put a decent single spring on the heads like a 901 comp or similar. The cam you have won't overwork a good single spring with damper.
