i have seen alot using brodix. i may get rid of both my iron eagles and pro comps. really liked the dart pro 1 heads but seen no gain over my pro comps. my combo again is 461 bbc,forged everything,rpm intake that will be moved in favor of single plain,rpm cam that will be moved for solid flat tappet. qft 950hp. wanting 600 horses at crank. want to run high 10s. my suspension is the lakewood traction bars, all urethane bushings, gear is 3.73 with 2004r trans.
brodix race rites or dart pro 1? wolfplace opinion?

I'd use the AFR 305s with the CNC Chamber option. The AFR heads surpass the Race Rite Ovals by quite a margin in power production.

Aren't all heads mentioned 320 or so cc's?
My opinion, they are too big for what you are doing unless you are planning on 8000
First choice, AFR 305 w/ cnc chamber
Second, either the RR rect or oval again with the CNC chamber.
Third, the 781's after being worked by someone that knows what they are doing
Maybe you can talk Rafal into porting them for you
I would also be looking at a roller for 600HP in a 454.

well my iron eagles are 308cc, my pro comps are 330cc, my pro1 darts are 310cc. i have no clue about the race rites. i know afr are priced way up there. looking to spend around $2000.
You have run all three of those heads and still can't run 10's?
That would be a big clue that your problems lie elsewhere in the combination.
I'de think your best bet is spending money on a solid roller cam and a properly matched 8" custom converter.
Of the 3 heads you listed, my choice would have been the Pro 1 310cc....for a budget head.
What head are you currently running and do you still own either of the others?

i own the iron eagles and pro comps. sort of own the pro 1,long story,i can get them if need be. was trying my own comparison of the heads. never had any of my combos to the strip yet but heads alone will not get me into 10s. i am thinking of solid roller but for the money i would rather go solid flat tappet and nitrous.

how do you like those pro comps? from what ive read, seems like the AFR 305s and a solid roller would get you to 600 easy
id try a solid roller cam first. seems like that would get you into the 10s by itself.
then if you want more, buy the AFRs from Mike.
let me know how you like those pro-comps... by the way, what are you running now?

well,probably going to get flamed but i love the comps! but this is my first 454 build. my machine shop guy give me access to put the comps against dart pro1s and i could not tell the difference. seat of the pants only feel,no dyno. the comps are better suited to a 496 and bigger. my machine shop guy runs them on his 489 and he loves them. my favorites are the iron eagles. i dont know why but my engine likes the iron eagles better.the pro1s are by my eyes a direct replica of the iron eagles, but my iron eagles give me a better seat of the pants feel. cant tell the difference between the pro1 and comp head. if i had a better cam i could do a better comparison.

Just curious but unless you have been on a dyno or to the track how exactly have you compared these heads??
To answer your sort of question ,, the Brodix are 270 & 290 respectively
The flow numbers on both are almost identical on my bench, one just has a bit more port volume & is well,,, rectangular
As was stated, if you have tried all three of the above heads & are not making at least 500+ I would be looking elsewhere for a problem.
The 330cc heads are way too big, the others are more suited to your engine.
If you cannot tell the difference between the Dart's & the ProComps, you need to learn Chinese
In my opinion these heads as they come are junk.
I am sure they could be made into something decent but at what cost?
email me, I think you will find the AFR's are not as spendy as you seem to think, at least from me,,,

How does the thing hook. If I read you suspension correctly I think you may be having traction problems. With 3.73s you sure don't want anything that makes power at 7000rpm. Have you thought about working with what you have just changing heads isn't a cure all for a combo that needs to be tweeked.

Not that Im tryin to stop you from upgrading to something better.....but I do agree. you got a couple heads there that ought to be able to do the job. The heads your thinkin about can do better(like the brodies or AFR), but the ones you got can pull it off with the right combo. I dont know if your spinning too much or your drivetrain and right or what(maybe just some tires and tuneup....who knows). But, with the right combo, you can figure out how to make the power with the ones you got if necessary. Maybe nothing at all is wrong with your setup. It might be perfectly well done. But to go as fast as you want, it might just need a little more everywhere else(....a tick more converter, cam, gear, hook.....all that stuff). Id run it for sure before you spend money cause right now, your probably fast enough that its very hard to tell for sure how fast you really are. And you wont know where it lacks till youve got some seat time at the track.
And oh yeah.....keep away from the gaint heads if you can. They look good on paper and far as how much air they can move and how much power the could theoretically make, but they hurt in terms of giving up grunt for top end that you wont gain cause your not rad enough or big enough to need them of use em right.

yep i figured i would get this kind of feedback. but hey the comps worked for me. only problem i see is the thinner spring pads, but my machine guy has a set with a blown 427 and .700 lift solid roller in a 65 chevelle and no problems, yet. thanks for the input. i wanted honesty and got it. just seat of the pants feel only no hard core evidence as to who was best. only dynos where i am at are engine dynos no chassis dynos. wish i had access to a chassis dyno. closest to me is columbus i think. will get a dyotune someday. thanks for opinions guys. i trust this site alot. the comps are a little rough as is but for a budget racer that can work them himself they would be a bargain imho. i am probably the only person to run them as long as i have with no flaws(correct me if wrong) and they work for me, but this is my first bbc build. it takes money to be fast sometimes does not apply i think. big blocks because of torque can take a heavy car fast. well fast to some. thanks again. by the way,i do have a chevelle i just bought,66 hard top came with 283 and is rough but all there,will be transplanting my big block into it.Just curious but unless you have been on a dyno or to the track how exactly have you compared these heads??
