[TurboS10]

Hey guys,

I am seriously considering going with a set of Dart Pro 1 aluminum heads when I put the turbo engine back together. I am curious is any of you have any good or back feedback or personal experience with these heads. I will probably go with the 200cc heads to avoid having to port my intake and to keep port velocity up. The flow numbers on the 230cc heads are enticing, but I dont know that with my combo it is necessary.

BTW, If anyone needs a good set of ported 487's, I know where you could find some.

so you won't be porting them, and you want to keep the total size of the runner unchanged and get the maximum flow numbers? In that case, I would check and see what AFR has. I know they're sort-of a bolt-on wizard's head, but I think they're probably the best choice for you, even though I hate recommending them.

here we go again about the magical AFR heads... ... look at the victors jr's compared to the AFR. THey flow almost as good on the intake side but outflow the afr on most exhaust lift points. This gives a better ratio of intake to exhaust flow. Down side is this is comparing the 200cc afr to a 210cc victor head... edelbrock claims they can support 550 hp right out of the box

I don't know how(and this is part of why I am not real pleased with this program) but The stock vortec made more power then either the AFR195 or Victor race heads with a 550 solid cam.

I know you are probably after the aluminium for the higher boost levels due to the heat transfer though.
I keep harping on it but PowerHouse racing ...they are the champs on bang for the buck.

Chris,
I am running Dart Pro 1's and have been for quite a few years. I am more than happy with them. Mine are bowl blended and slightly ported (I did the porting myself). When I was researching heads, I called a few places and that's what sold me on them. I called a head porter back east and he said, they are great heads out of the box and there really isn't much need to port them. Keep in mind he sold these heads and is a porting guru.

If you are serious about them I think the best deal is at www.herbertperformance.com Give them a call and they will set them up (complete with a bowl blend) the size valves you want, etc.. for ~$1150 (if I remember right). I just had a buddy buy a set a couple weeks ago.

I went with the 215cc on my 385 (which is the engine I originally bought them for) and it was N/A. They are still right at home on my blown 388. I can see why you would want to go 200cc with a turbo though.

Thanks guys

Royce, I can get a set setup with everything ready to bolt on for $925 which is WAY cheaper than I have found anywhere else. That is one of the reasons I am looking at them over the others. They are suppose to flow around 250/190 out of the box I believe.

I also have a set of them with 220 runners and ported for a few years and no problem with them.
Like Royce said they were pretty clean to begain with.

[camaroman7d]

WOW!! for $925 I think it is a no brainer. That is a smoking deal and I would be all over that. Keep us posted on what you decide. If you do go with them I would like to hear back after your engine is back together.

Another good thing is you don't have to wait 6-8 weeks for the Darts.

Chris,
They are a good choice. You may also want to look at the Canfield 200 head. For an as cast port (designed by HVH) the head flows excellent air out of the box.

Chris

[firestone]

That is a good deal at $925, Just be sure you know what kind of parts are being put in them. Some people will use really cheap parts that will break, in order to keep the price down. I know some people are against this, but I would still carfully look at AFR heads. Yeah, they are $475 more than you are looking at spending, but as has been said many times before, they are CNC ported. I would say that as far as performance per dollar goes, the AFRs would still be a better head. I dont know of any place that will give you a full port job for $475. I know the published flow numbers on the AFR and victor Jr heads are similar, but I have seen alot of cars with similar setups, with both heads, and the AFR combos always perform better than the unported Victor JR's. Thats just my experience.

Good luck
Adam

yeah I still think if you're looking for a certain size runner with the best flow numbers and you don't want to touch the head it would be worht it for the AFR's. THat way you know all the ports are standardized, have good flow numbers and you won't have to touch them. The only reason I would get an unported aluminum head is if I knew I wanted to have the option of porting later. You don't, and furthermore cant, so get a set size runner with the best flow numbers you can get-

What the heck are you talking about?


Killer, you have to remember forced induction engines don't work like normally aspirated engines do. The rules aren't the same for runner design or cc's.

Also, I have heard the AFRs can't be ported much more than what they come with stock. The Dart's I believe have more potential for future expansion.

[NXS]

Is what I'm saying is that I "built" three identicle engines

AFR 195s
Victor race heads
&
Vortec heads
all with .550" solid cams

The Vortec made more power than either one of the other heads.
I know this is not real life but the desktop dyno does give an idea to real world performance.

The Vortec heads..well they are "stock" so nobody likes them, but I know GM knows how to do it. Also it is a "myth" about Vortec heads not taking lift without machine work. If you know the secret a .540" lift cam is a drop in.

If you would like to "build" a streetable combination I would be happy to run it thru on this "dyno" using your heads vs the Vortecs.

[1BAD80]

Chris, hands down the Dart are the better heads for what your application calls for.
