Demand for ported 302 heads, is there any?

They can be ported to a 360 sized port volume, but unless they are going on a 7000+rpm motor and or go turbulent...why would you want to too?
Gasket matching them to work with a 360 intake is no problem.

Flow what and with what size valve?
App Demand will dictate that.

I've seen several members, including one posting in this thread argue me up against the wall that they are no good on a 360. That's why I asked you, because I knew you wouldn't give me some bullshit off the cuff answer. I knew you would know the real deal.
