Summit is having a mar-april special on these heads for $839. Are they worth thinking about compared to the edelbrocks i was already had my mind set on?

Which Edelbrock's are you lookin at? They are aluminum, the Sportman II's will have the 200cc runners, the Edelbrock's your looking at might only have 170cc. What is the motor you are building? What is it intended for?

Blaster...going to spruce up that small-block eh? Hey, did you ever get your hood re-painted and get your CI flapper installed? If so, how'd it turn out?

here are some Darts, in flow test flow a tad better, and have bronze guides..

Dart Pro 1 aluminums on Ebay are just over $950...just a thought :D

Im building up a good solid street car. I have no interest in taking it to the track and if i did would prefer to get great 1/8 mile times instead of 1/4 mile. Im looking for tons of low and midrange but want it to have good upper rpms. It will have no more than a xe274 cam or as low as a xe 268. also 3:73 gears. Looking for a good aluminum head at around $1000.

my hood is painted but flapper is still out.

I own a set, no complants here. I dont know about all that flow number stuff. I told the head guy I wanted a cam that best suits the heads, he sold me a crane hr-296 cam, and built the rest of the motor around that. the first time I got on the gas hard my car went sideways :eek:

I think your best bet for heads under 1000 is the Trick flow 23 degree aluminum heads. With an xe268 or xe274. Easily capable of 400+ hp and torque. Plus there aluminum and stay cooler not to mention lighter. Sportsman II's are good heads over stock but I think trick flows are much better. Dart iron eagles are also a very good head. Either way i think you'll be happy graemlins/thumbsup.gif

I would never buy any heads made by World Products. Everyone I know running them is very disappointed in them. Heck if you're just trying to build a street cruiser I'd suggest GM Vortecs. They can be found very cheap and with a tame cam like the XE274, decent gearing and converter you'll be flying and still daily driveable.

In the summit catalog it list the 23 degree trick flows as $1345. Is it cheaper somewhere else?

Now i see them for $969. The others were the big port ones. They look nice. Would they perform better than the edelbrocks as far as there low-mid range?

Edelbrocks do fine, have a 170cc runner, good torquey heads....but also for the same price, you can get aluminum Dart Pro 1's, in either 180cc or 200cc ruuners...

What would be the difference in performance with a dart 180 or 200 campared to a edelbrock 170cc?

Edelbrock 170cc would be better for a mild street only 350, the 200cc heads would work better on a 350 that see's the track alot, or a street and or track 383. If I was gonna invest that much money in some heads I would get some 200cc just because down the road you might wan't more power.

For your listed usage, you might want to look at AFR 180's. They cost more, but everyone says they are worth it. Get the 190's if you think you might want a bigger cam later on.

BEWARE OF ASSEMBLED HEADS!!!

I have two friends who have bought assembled heads from Jeg's and both of them have had to have aditional work,both needed a couple of guides and both needed a new valve job.One head was the I.E 215 and the other was the Sportsman II.

There are plenty of similar stories on the web so this is not a fluke graemlins/angry.gif

Jeg's buys the heads bare and then assembles them.

I know you are dealing with Summit,but I can't help but to think that they do things the same way.

Come to think of it I think that the I.E'S came from Summit.
I will call him and find out for sure.

I can't believe I am saying this after all the trouble I have had, but have you considered a set of pro-toplines? The 200cc pro-topline iron heads are about the same price as the sportsmans, but have a lot better port design and flow a lot more air, especially on the exhaust side.

Gotta set of WP motown lites (220cc) that came with the WP crate we wound up rebuilding after 200 miles. Heads had decent parts (Manley severe duty, correct springs, retainers), but the valve job was a hack job (3 angles here, 2 there, 1.5 on another - sick, sick, sick!). I'd have to go back and look at the invoice but I think we replaced 4 or 5 guides. All this on a seemingly brand new motor.

I think you've gotten some good datapoints here on companies with better R&D and customer experience on heads - AFR, Trick Flow, Dart, Brodix. Dart would be my #1 pick next time - I like their straight shooting nature of Maskin.

Best,
Mike

What problems have you had with your heads and where did you get them?

Ok...you asked for it ;) After it was all said and done...11 excessively loose valve guides, pushrods hit ports on, IIRC, 7 pushrods. Horrible casting flash in every port (like almost 1/2" tall "veins" :eek: ), and rough jagged edges around the spark plug threads in the chambers. It took a whole day with a air grinder and a carbide burr to clean this mess up. Oh, and several ports appeared to be cast about 1/8" off to the side of the valve seats. It all cleaned up...eventually. The heads was factory assembled and sold thru a U.S. retailer. I couldn't return them because I sat on them forever before finally building the engine. They did use some excellent hardware though. I know a lot of people have had excellent luck with them right out of the box, but mine was definately very crappy. Once it was all said and done, it did run very hard (nova in my sig). I say "did"...I've got the engine torn down again to resolve a oil burning issue that developed well after the engine was broken in.

:eek: DAMN
Crazy Ugly graemlins/clonk.gif

Wow,I was thinking of trying a set of their Vortec heads.
Don't know what I'm gunna do now.

I heard they were going out of business for a bit...
