Trick flow 270s or 240s on a 383?

If it helps I was in the same boat, .030 over 383, talked to Trick Flow and they said they wouldn't clear the cylinder bores. So I went with a set of Indy 440 ez. I'm on a budget so I got the cheapest ones, i.e. smallest port, which I think works well with the motor. Because, in my mind it helps keep port velocity up.
