PRC head install done. 
My winter project, PRC 220 heads, Holley tall valve covers, new coils, etc. I got it all buttoned up, and test ran it for several minutes. Everything seems good, no coolant leaks, so it looks like the head gaskets sealed. I also put in the Lunati link bar lifters, and Summit 11/32" .120 wall pushrods. Valve train is very quiet. So far, so good, now off to the tuner.

I'll take it to Hitech in Elk River, they tuned it back in like, '05, and seemed to be right on the nuts. I usually race at the Rock, have been since '99. I've known everyone there for years, so there's a comfort level.

I would be absolutely thrilled to see 425 rwhp!! I know that's small potatoes compared to a lot of the cars on the boards, but I still street drive mine a couple thousand miles a summer, and I don't trailer it to the Rock, which is 100 miles from my house, so I want to keep it fairly docile.

Nice choice. Are those the 225s? And a beautiful F body bay!
I wound up with 416 wheel on PRC ported 243/799 heads on a Mustang Dyno using a smallish BTR stage 2 cam. Depending on your cam I think you will easily make 425.
