Performer RPM Magnum heads?

Just for kicks I want to say that I went with Eddie Performer RPM Magnum heads on my 408 stroker. I had them cleaned up (out of the box) and port matched to my LA airgap intake by Hughes (who also drilled them to take the LA intake). I went with a version of the GM rocker at a Magnum ratio of 1.6. BTW... I had to clearance the pushrod path just a bit.

Anyhow with no tune and a 3500 stall (off the foot brake) I see 7 sec 1/8 in my lite street Dart in the nineties. I think I could tune .5 out of it but really just enjoy the car on cruise nights these days so...

For me I like the Magnums, the chamber and the valve size.
