Default About to buy Afr 205 heads...... But they're milled to 53cc
I have a 383 stroker ls1. I'm thinking if they are milled that small that they for for a completely different setup and would not work well for me. Looking for input. Should I buy them for my setup?

Whats your setup exactly?? I've seen a guy
on here before whose heads were milled to something crazy, maybe 48cc?? But, his application was strictly e85, race style motor with Compression over 14:1.

You can kill airflow when you start to mill heads that much. Or have issues with the manifold even fitting properly. 66->53cc is a .078" mill.

Yes, the intake air flow can be affected with too much milling.
