There are many springs that you could run with that cam. I am a fan of PAC springs so I'll throw the 1218's out there. They are comparable to the Comp 918's but they are made in the USA and don't have the poor track record that the 918's have had in the last couple years. The Patriot Golds are also an excellent choice. If you search on google for Crane 10308-1 you may find them for sale somewhere that hasn't yet gotten rid of their stock.

The patriot kit i am talking about has not just springs but titanium retainers, locks, seals, and bases all included. If you buy another brand of springs you will have to get everything else seperately and in the end cost your more. Alot more.
if you can find the crane 10308-1 kit id run that or even the 918's for the cc306.... theres no need to run a .650 lift spring with this cam.. at 1.5rr its like a 510/540 and with a 1.6rr its a 544/576 any spring with a 600 lift will be fine. look around in the for sale sections on here. i just recently sold my crane dual spring with retainer kit for like a hundred bucks.
