I'm pulling the 350 out of my Toyota this winter for a little beefing up. I'm rebuiding the whole top end and focusing more on the heads. I'm installing 1.5 roller rockers and a Comp Cams 270H Extreme 4X4 cam, I want to upgrade the valve springs but I don't know whichs one to use, any suggestions?.
