Progress marches on.

Ede heads are still as effective as they ever were.
What has changed is they’re several hundred dollars more that they once were....... and there is now a competing head(TF) that offers more performance for less cost than buying and modifying the Ede heads to reach equivalent flow numbers.

If I were looking to build a hot street/mild bracket engine, and TF240’s were unobtainable, and there were RPM’s on a shelf somewhere, and I felt I’d be ready for heads before the TF’s were available........ I’d just get the RPM’s and modify if/as necessary.
