If he used the stock springs the problem isn't the heads, the problem is you. Those springs are not mae for the cam in the car. It's not shocking that theyd float... if thats your problem.

I can't believe manufacturers still sell heads and say the springs are good to X amount of lift. Valve springs don't work that way, and AFR come with shitty springs to begin with. Call the cam manufacturer and buy the springs they say you need for the cam.
