I'm still debating on which heads would be best for my set up. Im getting the following
Eldebrock Performer or Cobra intake
24# injectors
190lph fuel pump
70mm MAF
65mm (or 70mm) Throttle body
2400 stall TC
1.7 Roller rockers
E303 cam
mac headers

I just cant decide on a pair of heads!! The Powerheads (www.powerheads.com) are ported stock E7TE heads and they flow better than the GT40's but dont have valve spring lift after .500 like the GT40's do! I havent seen any numbers on the DOOE heads. But they are the 1970 351 heads with 1.90x1.60 valves, and the smog bumps and exhaust hump cut out. Which heads what you guys get with the mods I listed? (BTW Im talking about the regular GT40 heads, and I found all my numbers on this chart comparing all types of ford heads.... www.pinn.net/~nascar/fordhead.htm)

1MNPNY ,,IMO POWERHEADShas bumped up their figures and lowered others.
I've ported at least 20 sets of Dart Windsor Sportsman heads,and always do a before and after on my SF 600 flow bench and stock Darts out of the box flow between 240-255 cfm at .600 lift with 2.02 1.60 valves and with about 2 hours in each port they flow from 280-305 cfm (varies with castings)

So you see I would go with GT-40 or if you have the budget get TFS

But the magazine MM&FF tested them back in 1999 and they got an extra 39HP and 38lb/ft torque just bolting on those heads.

Magazines!!!!
Lets not go there please

Magazines write what you tell them to
When Ray Barton was in MTL Mopar Magazine came up to write an article on his shop,they asked Ray so what should I write,Ray said that you're writing the article and the guy said that he writes what ever Ray will say .
Ray told him alot of crap and in the next issue right there in black and white that guy wrote the same crap Ray told him so please don't say Magazines
