We sell both. Some customers like KW and some like Ferrea. Yes they will both work with each other.

I've tried contacting Ferrea an haven't had any luck. Do the valves use stock retainers? I'm like "hitt" and have the KW springs already. Do you only have them for the 700? I see that is a 4 valve not a 5 valve.
