Title: Which heads for the K10 Suburban
Post by: Jims86tpisub on January 08, 2009, 05:03:59 PM
The engine is a 86 350 Goodwrench replacement, topped with TPI.
 I  have a set of new 193`s in the garage, and,  I have already posted on this subject, receiving good advice from Zamboni, but I also wanted to get some opinions from other members. I never buzz the engine up far beyond 3500-4000, so I think my Tuned Port setup should suffice, with a tune of course, after the parts are decided on. Cam suggestions greatly appreciated as well.
Vortec heads omitted, due to crazy expensive lower manifold from Edelbrock, and SDPD.
Thanks!
Jim

i voted world S/R torquers because they have a bunch of good reviews on them and at a fairly good price.. great all around mild performance head.

Me too.

EDIT; Dart S/S are cheaper!

I would go with the Dart Iron Eagle S/S heads. From what I've read, they can produce a little more power with similar setups than the S/R Torquers. They can be bought too for $650, assembled and shipped! Choose either 165 or 180 cc intake runners and 72cc or 64cc combustion chambers for no extra charge. You wouldn't need the 2.02 valve upgrade. The 1.94s are fine.

I have the Darts (165, 72, 1.94) and like them very much. I only wish I went with the 64cc chamber. With your setup and the TPI, I'd say go with the same as me but with the 64cc chamber. I got mine from Indy Cylinder Heads (Aerohead) for $650 + 100 shipping but I found them elsewhere for $649 shipped. Competition Products I think it was called. They are online. They perform very similar to the stock Vortecs but come with higher lift valve springs (.525") and don't require the Vortec-specific intake and self-aligning rockers.

Hey Chad,
   Do the Dart heads have exhaust crossovers for egr? I cant determine from their website if they do or not.
 Thanks,
 Jim

I think they do. This is where I got them from and it says it accepts all stock equipment. I know I see the heat crossover passage on pics of my heads that I took before I put them on, but I don't know if that's the same thing as for the EGR.

I like the RHS Vortecs
It is dual drilled for vortec or std intake manifolds

$629 assembled

^ Also an excellent deal, especially if dual-drilled!  I know a guy with a 355 that has those heads in a 89 Mustang LX coupe (yep, SBC-powered 5.0  lol) and it runs high 10s. Lots of other mods and juice too, but those heads can make some power.

For the cam, what are you running for an ecm? Is it stock?

Perhaps you should take another look
The RHS vortec is not a GM casting

The prom is stock, I also have a prom that is supposedly burned for my app., but have had problems with it.
I was thinking of something like the comp 260 cam, or like you suggested my other post.

Check these (http://cgi.ebay.com/ebaymotors/New-Dart-Iron-Eagle-64cc-SB-Chevy-180cc-Heads-10120010_W0QQitemZ120319718753QQcmdZViewItemQQptZMotors_Car_Truck_Parts_Accessories?hash=item120319718753&_trksid=p4506.c0.m245&_trkparms=72%3A64%7C65%3A12%7C39%3A1%7C240%3A1318) out.  That's a great price for a set of bare iron eagles.  Note the reason for this, in case you don't read the full description, is that they are cosmetically blemished.  I'd check with the seller on the details of this blemish before buying, but it sounds like a great opportunity to capitalize on Dart's little mistake.

Those look like a sweet deal, But I NEED the exhaust crossover.
Thanks!

Oh yeah, for EGR.  I wasn't thinking about that, just got blind-sighted by an awesome deal.

You can find good used SR torquers on Craigslist and eBay sometimes they have great swirl and respond really well to mild porting.  But, I'd never pay the current suggested retail for them, may as well get a set of aluminum heads for that price.

Copy That!
 Also,
I just called RHS regarding Their "Vortec style" heads....The exhaust crossover is not drilled out, so they are out of the question.

If you run the aluminum heads, you can bump the compression up to 10.5 and keep it on pump gas... ;)

Patriot sells a Vortec head that looks just like the RHS Vortecs

I called the seller and he sez the exhaust crossovers are blank


For $279 a pair (bare) this hard to pass up

Ok guys,
 Thanks for all your valuable input on this subject.
   With money as funny as it is these days, I have decided to use the 193`s(Never Used) that I got for free, and I scored a center bolt lower TPI intake to top them off with, all which are at the local machine shop getting cleaned up right now.
 
I did budget for a cam, and have a Comp 12-388-4 sitting here waiting to be installed. Got a Fel-pro top end kit as well.
 The whole shebang will be topped off with some new GMPP valve covers P/N 1235530. All purchased from Summit.

 Maybe down the road, whenever we are out of this mess, Ill either go with S/R torquers, or maybe by that time, some vortec heads, If I can wrap my brain around the external egr, and massive chip tuning process that it will require.
 Thanks!
Jim

10-4 on the budget thing.  If I were building the engine I'd use the s/r torquers because they promote great low end torque and it sounds like that's what you're looking for.  I also don't think it's enough of a difference compared to your 193 heads to make it worth the money to buy another new set of heads.  I don't think you'll be disappointed with your decision.
