Dart iron eagle heads

Looking at iron eagle platinum 200cc heads for my 400 sbc. I have the old 292heads on it now. Comp xe284h cam (507/512 240/246 @.50) rpm intake, headers, 4 speed and 4.10 rear gears. Just wondering if anyone has used these heads and if they like them. Just want to go faster! Don't we all.
Thanks, John.

I have the 215cc heads and the same cam in my 408. The engine has a really flat torque curve and pulls like mad. I like them.

I put the 215cc heads on a stroker motor for a friend, they make good power. Go cost you though!

Have the Dart Pro 1 Aluminum 227cc on my 408, treat a 400 like a big block, get the biggest heads you can afford.

Dart heads are good heads. I run Dart Pro1 355 CNC heads on my car. I think the 200's will give you a big gain over the stock 170 port heads on there now. I don't think you want to go much bigger. You have a small cam in a fairly large engine so rpm will be lower.

I don't see where he says what size engine he has. None the less I have a set of 230 Plat on my 355. I had 215s on it last year with a small hyd roller and 10.5:1 compression and put down 421hp and 435tq. So the heads do great for being a cast head. All I can say is spend the money on what you really want. If you are really wanting a set of AFR's then save your money and buy those heads. Don't spend $1000 on a set and then turn around and buy another set that are $1500 later on.

are

the 292's ported or stock ? the darts are great heads ,, the 292's can be great heads with alot of work ,,, i've read a good bit on it ,,, some will say a good set of 292's will out perform a set of 200 darts the swirl pattern ,,, things like that they'll speak about ,,, but these were likely 292's ported by the very best ,,,, they are getting old , ,, but i think i'd keep them if you get a set of darts ,,, conversation piece if nothing else

Thanks for all the info. The 292's that I have are 1.94/1.6 heads. And yes the 1.6 are not the stock valves. The guy that had them before me did a quick pocket port and cleaned up the intake runners. I cc the head and found that it's 165cc intake and 60cc exhaust. The heads are in great shape but, I was looking for something with a bit more performance. I am thinking that a 200 cc head will work well with a 400ci motor. Kind of a street/strip. With the heads last year the car ran an 13.30 at 105mph with a bad 60 foot times. Was hoping to go faster!! I figured dart heads as listed with exhaust polishing would help in that department. Thanks, John.

Ahhhh the old sbc cylinder head topic well must say the steel heads your looking into are a good head and i would not go any smaller than a 200cc with a 400 but id recomend for a few bucks more a set of new pro-filers
http://www.profilerperformance.com/sbc-heads-176.html

Grab a set from pro-filer direct and get and amazing head and when you decide you want to go a lil bigger theres plenty of head to grow into send them off to chad speiers and have him work them for you!
I bought a set of 210's for my 406 directly from chad and was real reasonable
http://www.speierracingheads.com/

But like mentioned above someone mentioned get the biggest head you can afford thats the last thing you want to do talk with some one like chad and get a head built for your needs and have a perfectly matched combinationation and dont leave any power on the table get a head that will work for you where your going to be using it!
Good luck!

i would go with a set of 210 runner heads with all the 400 sbc i've put together they seem to be the best bang for the buck i perfer dart and afr there both good products. also the pro comp heads aren't bad either for out of the box perf. i do like a set of rhs heads they have good casting quilty and are very easy to work with. good luck in your quest to go fast just stick with a 210 to 215 runner that's my advice killer 70 ss nova

Thanks for all the input! Just doing alot of looking on the net, it looks like the 215cc iron eagles are the way to go, not the 200cc. I just dont want to loose to much bottom end power. As for the 292's I think I will sell them on ebay or at the swap meet in spring. Have you ever heard of anyone polishing the exhaust port and combustion chambers for more flow? Thanks.
