they flow 405cfm@.600" and are baller, and rightly so at 8500 a pair plus valvetrain.




not sure if they are a sponsor or not, so im not going to post their homepage

just wait the 3 years and change for the gm dohc heads. 2011 they are supposedly going to ohc

The nice thing about these though is they're "designed" to work with existing technology. I'd love to see some independent results out of them.

you'd need no hood to get that thing to clear!

No quench and some decent valve shrouding. I think they could have done better. In the 25 years of racing and building cars, I have NEVER seen a set of their heads on a car. Just too damn expensive to be a test case.

Those heads are constantly referenced and hyped on this forum...they are not what they are cracked up to be. IMO they would be a waste of money. If you have actually hot rodding experience with 32 valve heads on a v8 you would understand why this is not the hot setup everyone thinks it is or will be. If money is no object then you can get a little more power for a lot more money. This arguement will go on for as long as we have IC engines.

How does that work with pushrods ?

ya its direct bolt on. i just thought there was never a motor that could take advantage of the flow. id think a 454 with these heads and a sheetmetal or itb's would destroy ****, come close to 700rw, and be very stealthy and driver friendly. but then again thats a 25 thousand dollar motor

what is your point other then it cost's a fortune and the average man like me can't afford it-

i am expecting my 427 lsx engine to lay down 580-640 rwhp for a total cost of $14,000 us complete+$1250.00 us for a twin plate=$15,250 us

or do it with these heads and lay down 700 rwhp at a cost of $25,000+clutch=$26,250.00

so if i am off 50-100 rwhp i would be happy while my pocket smiling at me with a spare $8,000+

the cost is a joke and i dont feel i am the only one-

who here would rather save money and still make decent amout of hp and trq while still having a lot of change lefted over- i know i would-

[QUOTE=njc.corp;7880183]i didnt say it was reasonable, i just want to see some one do it

[QUOTE=njc.corp;7880183]Yeah, but besides the high price tag (the price I got from Russ Aroa a month ago was $10,000 for complete ready-to-bolt-on), the customer service and support is supposed to be the worst in the performance car industry.

I'm putting ETP CV heads on mine. Customer service, quality, tested and proven. But same price.

Their issue isn't price. They have a horrible track record for customer service and inability to deliver the product. Their 32v LS heads are about as real as the Easter Bunny. I'm doing All Pros on my 422 LSx twin turbo.

They actuate a forked pushrod that opens and closes two valves at once.

Supposedly they are under new management and trying to rectify their former problems. Good choice with the All Pros through. Bob @ All Pro is really helpful and knows his ****. I just ordered my set of hurricane heads last night.

The heads are definately real.. When I was out in LA last month I took a drive by their shop. (In Chatsworth, LA, right off of Conoga blvd) They had a motor on an engine dyno doing some testing.

I have to say though. The shop was a dirty hole in the ground. Although the owner was really cool, it was not a place I'd buy any product from.

I looked at the heads. Both assembled and bare casting.. The one thing that stood out was how horrible the surface area was. It would require some SERIOUS work to get them to function well. One of the worst parts of the heads were 2 things. 1) Valve Shrouding. Man, was it bad. 2) Pushrod angle.
These heads were NOT thought out. IF they let one of the reputable head companies to take over the R&D, I think they would be a serious player. If not, they are a joke..

It would be interesting to see how much the sound of the car changes.

I'd love to hear it.

njc.corp

well thats even worst-

njc.corp

i dont care what kind of business it is-but if selling $8,000+ items i would make sure my shop was tip top-

it represents the nature and attitude of the shop itself-

but on the other hand-we have all seen dirty shops do good-imagine if they were clean and ran it like a business-how much better would they do-

cleaner and pretty shops always do good because the a serious customer can see where they spend and how they spend their money-

[QUOTE=Hennytime;7880604]sorry for being a bit rude towards u-

i was just stating that this topic is boring and has been talked about too many times-

from the replies i think they have a better chance pushing **** up-hill-

the replies state that their customer service is worst then the price tag-

so i dont think anyone will be in a rush to buy or do this heads quickly-


also some of the etp- and allpro product line come's close or even better and they have good customer service from what some freinds tell me and also from what u guys say and write on this forum-

the ? is why would anyone shop their if they allready know the outcome-

Does anybody who's not associated with Dominion/Arao have a set of production LSwhatever heads on a running motor that bolted on and performed as advertised? It's the same old BS they've been telling us for decades; I still say these heads are no more real than the Easter Bunny. Buy 'em if you want 'em...but I'm an old grey haired geezer who's been around the block enough to know better.
