Personaly I think and fell You'd have better luck with Mike. At least is on the up&up with out a dout.and again I personaly wouldn't deal with Deppe.
And besides That Mikes Head is much more up to date and More HP(gain) then the Older Deppe head.

And yes 4000 is going to do a lot more then a grand.Because your talking Just shy of 4000 for
His stageIII head. Plus intake valve cover your
exhaust so on(extra goodies) to go with it.
Which still one of the BEST Bangs for the Bucks.

If you was to spend that Kinda money on that Head you wouldn't be shooting for 14s I'll tell you that Much.
The Older head was good for 2hp per cubic inch.
That head was on a 230 that Put out 460hp it had a 800 lift cam and feed with 3 660 Holleys.
