I was tossing around build in a 406 with vortec heads mostly because i have a set lying around. They have the .550 springs in them. My question to some of you out there is are you using these heads? And how well are they performing for you? I know I could go to better heads but with the budget and the overspending everywhere else on the nova I will probably have to use them any way. Any input would be greatly appreciated. I ended up having to sale the ls1 so hopefully this will make me happy.
