What can be done to improve the performance of vortec heads? Do they need anything done to them? What is the smallest chamber size they can be milled to?

Thanks
Jim

Clean up the ports, cut the guides to fit higher lift springs, install a swirl polished undercut valve. Max milling depends on angle cut or flat mill.

Stay away from any major porting - many have spent a lot of money on major port jobs for the heads only to gain 1-2% more flow for an $800 job...
