ARE heads ???
I'm about to buy a set of ARE Street Eliminators. Am I making a wise choice or should I go with a different set. I have a custom grind cam 219/228 @50 degrees, 279/287 total duration with 112 centerline. I was told these heads would compliment my cam and nitrous system very well. Any advise would be helpful. Thanks guys. :cheers:

I hear, I could figure that out either but Matt at Exit28 swears they are good. One step down from Stage II heads I guess. I'll see if I can find the spec's and post them..

Re: ARE heads ??? (Fast Frwrd)
Here are the spec's as promised..and I quote
"ARE's Street Eliminators are the way to go. These heads come with brand new stock valves (2.00/1.55) and retainers but have Comp Cams 918 valvesprings that can take the abuse of higher lift camshafts. These heads are hand ported with ARE's custom port design."
Now what do you guys think..

Street Eliminators are ARE's new entry level heads that offer the best bang for the buck performance.

Matt-
Not flaming you. Just wanted to make sure I am doing the right thing.

These heads really do offer an excellent performance gain over stock heads. The stock heads do work pretty good, but with some some custom port work they can be made to work a lot better.
I believe these heads are worth at least a good 20 - 30rwhp over stock heads with just a cam.

Re: ARE heads ??? (akw408)
Matt is definately not doing that. He has 1650 and more expensive heads. I was really looking to see if anyone else had these heads and what their results were. Matt has been a great guy to deal with and has helped me out tremendously. He is one of the few vendors, supporting or not, whom I trust. I will be going to the dyno tomorrow to get a baseline with and without the nitrous. I will aslo be doing the same after the head/cam/programming and postthose results as well. Can't wait for track time.

Re: ARE heads ??? (Fast Frwrd)
I REALLY think that these cam specs are not the best. As a matter of fact, I woud go as far as to say that they are not very good at all!!! The exhaust port on the LSx heads is so good, you just do not need to go that large on the exhaust duration and DEFINITLY not a large split in duration like that!
You will have clean air and fuel going out in your exhaust with this cam and wasting efficiency.
I would suggest a symetric camshaft for a heads and cam LS1. At the most, go with a 2-4 degree split.
JMHO,

Re: ARE heads ??? (akw408)
Chris or Matt- what would you recommend with these heads then. My sig has all the mods I have done. I haven't paid for the cam yet (GM HOT CAM) and I can go with anything else I want. The mechanics will put it in regardless. let me know before it's too late. Don't forget I have a 100-150 shot of Nitrous (Wet)

Re: ARE heads ??? (Fast Frwrd)
The camshaft you go with is going to be a function of your intake, heads, and exhaust - the intake is pretty much consistent on most lsx engines, but the exhaust and heads can very by a large amount.
At a set intake flow amount you are going to have a relatively fixed amount of exhaust to evacuate - with a better exhaust system / exhaust port on the head this requires less exhaust duration - giving you better idle/drivability qualities. With a poorer port/exhaust configuration you are simply going to have to open the valve longer to evacuate the end gasses from the combustion process. The LSx engines, even in stock form, have a great exhaust side, and it is normally much better after ported - hence Chris K's suggestion of a single pattern camshaft. (which I would definitely agree with).
So what does that mean? Basically I would talk to the sponsor/shop your purchase the heads from, and let them know what your performance goals. Have them suggest a camshaft, as they are going to know the heads the best! I would also inquire about other vehicles running setup's similar/the same to what you are - this is really the best indication you can get.
