OK, this subject has probably been beaten to death (sorry). I have a somewhat limited budget, maybe $1500-$2000 max for heads. What do you guys think are good street head choices?
10.5 compression with 452's, Comp Cams Xtreme Energy 21-224-4 274/286 duration, 488/491 lift, 230/236 duration @ .050", 110 lobe separation, 1-5/8" headers, six pack, 3.91's (likely going back to 3.23's or 3.55's since I don't have overdrive), 4speed, power brakes, power steering, no A/C, nitrous. I would like to run a faster 1/4-mile but keep the car completely streetable (99% street driven).
Should I home port some 452/906's? Larger valves? Edelbrock? Stealth? I'm "guessing" Indy & B-1 type heads would absolutely kill my bottom end. What do you think?

Thumperdart, I see your car is pretty fast. Do you run a cam as small as mine? How much to rpm's cost about?
Ice-Eagle, what makes you say stealth heads because I have a six pack?
Does anyone have some track data on the same car with different heads? Obviously, I'm looking for something "streetable" to compare with & not a blown alcohol engine.

352's ?? do you mean 452's ?
Do yourself a huge favor and shitcan the open chamber, iron head unless you race in a class that requires them or you have KB step head pistons already.
Sidewinders are a low cost upgrade , or the new trickflows.
running up my post count some more .

i was just looking at what trickflows would be from summit if i could get a 20% coupon. then i remembered about the sidewinders. one difference beetween the two is 210cc vs. 240cc intake ports... with a small cam the sidewinders would probably be fine. here is a link http://www.mopartsracing.com/parts/Sidewinder.html

CNC ported Stealths or Trickflows are very similar in performance.
Stealths are straight plugs whereas Trickflows have angled plugs
Stealths have open combustion chamber whereas Trickflows have a little more modern designed chamber.
Stealths look like a stock head on the end Trickflows do not.
I've run CNC ported stealths all over on the street and run 11's @ 117 mph with them in a car with 3.55's.
Both work equally well on a street/strip car.

How fast do you want this car to go on the motor and on NOS? What year and body style are you working on? The primary pipes size is probally going to limit how much power your motor will make on N/A as well as on the NOS  I love 4 speed cars, I'm working on putting a 1966 Dodge Coronet Deluxe with a 440 motor and NP 833 O.D. tranny together this summer, I also have a 1969 Dart GTS 383 4 speed car to drive in the meantime  To many toys and not enough time to enjoy all of them

Ice-Eagle, what makes you say stealth heads because I have a six pack?
Has good flow numbers for you 6 pack. Pairs up really good.

What size engine is this, what do you run now, and what do you want to run? 1 5/8 headers are small if this is a 440.

The heads are 452's. It's a .030" over stock-stroke 440. Pistons are TRW L2295's, but the domes have been milled, so maybe it's just 10:1 with .035" head gaskets (?). It runs on 93 octane. I run 1-5/8" headers because the engine is mild & I destroyed one set of Hooker 2" primaries & two sets of Heddman 2" primary headers bottoming out on potholes. I have 4" more ground clearance now.
Definitely only need good head flow numbers only to .500" lift since the cam isn't any bigger. Aluminum heads would be nice if I can afford them for the extra "forgiveness" to nitrous and pump gas... if I can afford them. However, it would be stupid of me to spend $2000 on heads that slow the car down or have no affect, right?
Will trick flows/edelbrock/rpm/etc heads do me any good at .500" lift vs. stock? Slow the car down? Are larger valves worth the money at .500" lift? I'm thinking my options are:
1. bone stock 452's
2. home ported 452's
3. home ported 452's + larger intake & exhaust valve
4. aftermarket head
Everyone would like to have some new aluminum heads, but whatever money I save on the heads goes towards a second stage of nitrous or some lighter rods/pistons or ? Honestly, I think $1500 ready-to-bolt-on is more my budget...and that's a stretch....just skip lunch for 6 months.
