Small Block & Big Block Chevy Specific - Vortec Style Aluminium Heads??????

Im looking for a set of decent aluminium vortec style small block heads. I have been doing some research and cant come up with anything. Can anyone help me with some ideas?? Thanks

Edelbrock etec's are a direct vortec replacement

I have a set of GM Aluminium Fast Burn heads now. Would it be worth the money to have them ported and re worked?

I have a firend with a set of fast burns on a 406, it runs great but he is looking to swap for some other castings, they have potential if they were ported.

AFR has a 180cc Vortec Head
World Products just released two different sized intake runner Vortec alum. heads here not to long ago (I think 215 & 235).

Thanks for the help everyone.

FastBurns can flow upward of 280cfm when ported with no problem. PORT 'EM.
