I need to machine the valve spring seats on my vortec heads what dia. does it need to be and how much material needs to be removed or can be safely removed.
I have 350 short block bored .060 over and have a few choices for heads I have on hand. A set of 305 heads I am porting that would probly run tbi, a set of l98 vette heads with all the tpi setup and posibly a set of vortec heads I might be able to talk a friend out of that the tbi came with...

Thanks man. You said carbed I would be running vortec heads and the only have one vortec intake a tbi intake. Does the tbi setup run a knock sensor and if it does would that help stop the detination.
