Performer Jeep 4.0L Cylinder Head

The Edelbrock #50169 Performer Cylinder Head is designed as a bolt-on performance upgrade for 1987-2006 Jeep's with a 4.0L inline six engine.

Anyone used this on either a 4.0 or a 258?

I'd be putting it on my 258 with MPI. "More flow" probably won't make a difference on a 258? Some say opening it up too much can actually DECREASE low rpm torque due to decreased air pressure... Anyone have any experience with whether this is true or not (in a significant way)?

Thanks,
James
 
Update, they are saying it is designed to improve torque and power across the rpm range, even on a stock 4.0. And can perform even better on a 258 block with MPFI.
 
Debated about it on my 4.0 after we changed the head out on a beach one day and before I went down the path with a stroker swap. Certainly seems like the stock head left a lot of room for improvement.
