What valve springs with a 204/214, i hear CC980s a lot but am not sure if they can consistantly and reliably rev to 5800-5900. I've read the kirbans springs are too stiff, but im not running a stock cam and the motor likes to make power above 5500 or so. Also this cam has about 15,000 on it so it should be well broken in. What would yall recomend. I broke a spring on #5 yesterday and would like to replace them all as i don't trust them. I can't remember which springs my engine builder put on the heads so i will give him a call tommorow to get the info as i can't find the spec sheet. What about the Speedpro/sealed power springs? K-motion? Thanks guys.

Well after talking to my engine builder i think im gonna go with the sealed power equivalent to pioneer 943s, the VS-739Rs. I talked to my engine builder and he recomended something a little more than the 980s for what rpms my motor sees on a regular basis.
