You would have to research Cali's emissions laws and how they apply to swaps. At a minimum, any heads/cam you use would have to have a California E.O. Luckily a lot of good parts have this, including performer heads from Edelbrock:

i was thinking of ported vortec heads, a edlebrock performer plus cam. and a edlebrock intake. will i have to get the vortec heads drilled for the 400. any thoughts would be appritiated.

Yes. It's not hard, I did it by using a head gasket as a template for hole locations, and did the deed with a hand drill.

I think Dirt Reynolds did the Vortec on a 400 install. Might want to hit him up for some info. He hangs out here and at NastyZ28.com.
