What is the part number for head's I will need to put on my 350 and will they bolt up to the Edelbrock Tbi intake.

 

You want the 4277A, IIRC. '87 and later bolt pattern, 76cc chamber. Ask for them to be set up for up to .550 cam lift. That will give you flexiblity later on with cams.

They will fit the Edelbrock fine but if I was you I wouldn't spend the money on either. If I were to do it over again I'd get Scoggin-Dickey's Vortec heads and TBI manifold. Hook up the EGR and AIR through the headers (if you need them).
Eventually, you'll want a bigger TBI, BB or Holley. Then the Edelbrock will be useless or need to be bored out. I just bored my stocker yesterday, came out great. I'm glad I didnt spend my money on a replacement.
I understand the Holley has 2" bores but a recent thread has someone (can never remember names) going through fits to get the cables correctly mounted.

 

keep in mind that you could go with a smaller chamber and bump up your compression ratio considerably...
