I bumped this up about a year ago. I see that the HIP'd casting is available and pricing is around $1100-$1200 per head. Edelbrock #770469. Has anyone finish machined a set of these yet?

You may want to call Richard at WCCH since he started this thread. If he doesn't have any information I would try Curtis Boggs at RFD 703-339-1039. I know he has done these heads and they should be available.

I talked with a couple people about these... there's 450+cfm potential with the ability to make a port with the cross sectional area to support even the biggest of tall deck high rpm applications.

I'd really like to put a real all out motor together someday with these, see what they can do.

Someday.

I would imagine these could put you in the 1100hp range N/A with .950 lift or so. But I would say get ready to hold on to your wallet when you order a pair. These would most likely be on the order of $7k a pair which is as much as many of the guys on here have in their whole engine. Once you are said and done I would guess $25k+ depending on whether you are running a dry sump which will put you over $30k to do it right. (...all the sudden I just pictured that clip of Tupac when he was counting 100's from one hand to the other).

I know. BUT, then again I'm looknig at a clutchless liberty to put behind the 408 I will have about 12 grand into... 12 grand for a tranny/clutch/bellhousing/driveshaft... 12 grand in the motor. That sounds a little off

BUt, if the 408 goes as fast as I think it will with the driveline and 2800 lb raceweight I should be at... I'm sure a motor like that would well... run some #'s.

im with you guys on these heads i found out you can make these a 8.5 degree instead of the 8.7 they are im half tempted to pull the trigger on these bare castings after seeing a flow sheet from a head close to 500cfm at .700 lift i was very inpresed with the potential

I've seen one flow sheet that was from an early set, the thing that impressed me was that they were at 300 flow right before 300 lift, and at 1 inch they still hadn't stalled out.

That to me, means it's gonna move a TON of air. I liked that the exhaust was really good on them.

The bad part is the cost, I can see the top end being in the 25K range by the time it's done. But, unless you're running FI, the power is made in the heads... if you have to spend alot, best off on the part that makes the power!

^ I wouldn't figure 25k in the top end. You'd figure the heads alone are $2200, estimating the work on them as $2000, titanium intake valves $1000, SS exhaust $200, big 1.550+ springs, retainers, locks, seals, $600, custom rockers $1500, pushrods $140, lifters $600, cam $450, custom sheet metal intake manifold $2000.

You'd be looking at $10690 and I think that's a reasonable estimate. I still think some of that is comparable to the current prices you'd be looking at something currently offered, but with way better performance.

I think the port work, valve job and whatnot will probably be more like 7000 if you really go all out and have them hand finished and really done right.. a 2000 dollar port job, I don't think is gonna make 1200 hp n/a, and face it if you're going with a head like this that's what you're aiming for.

Rockers I think would be more like 2500, I can see the springs being more like 1000 bucks too, I don't know of any springs I'd run with an inch of lift on an agressive cam that are 200 dollars. Lifters would be about 1000 too, pushrods I would run would be a tapered manton type and those are probably more like 400, and the intake I'd price at about 3500 not 2000.

Not even close. Big dollars and one off custom everything to make them work. Everything? Yes everything: headers, head studs, manifold, gaskets, spark plug tool, etc. As an example, the only available rockers for these heads are jesels that go for a cool $2600. If you want a fast n/a car, build a big block chevy and have enough left over to buy a new duramax 2500 to tow it around with.

somebody needs to make 4v heads for the ls series motors,

i know aero makes them, but i heard they never deliver their product and they are way too expensive

if somebody can make a 4v head for around 5000bucks i would put my name down on a set of those

I have always wanted to see a single cam pushrod 4v small block chevy(ls engine).

Not sure if its worth it to make one tho, the 2v heads that are being made like the ones in this thread have plenty of potential.

I am ready to see a set of the edelbrock heads and the dr heads on a car and see what they can do.

Would expect the prices to be the same with you having done all of the guinea pig work. As in are the rockers really custom if they've been made before? They'll probably still charge you the same for them even if they have the information on hand.

Who did you have do your heads for you? I'm not at the point to be spending this kind of money when my car is a tin can, but I have been thinking about components. Were your heads done by hand or CNCed? If someone could write a 450cfm CNC program for these heads and price them as ready to assemble castings for $4000 I'd guarantee they sell like hot cakes.

That's about what I have invested for the top end in my 830hp N/A build.

ETP C5R 265 heads
Jesel J2K's
Valves, Springs, Retainers, etc.
Valve covers
Pushrods
Lifters
Beck Intake

I'd say that going with the same hardware on the Edelbrocks would cost a few bucks more since they need a ton of R&D with labor to bring them to their full potential. Personally, I am considering them unless I can make mine flow better than they do now...

There isnt a chance in hell these castings would go for 4k assembled..Im sure the cheapest you could get by with them with "basic" parts is 6500 or so. Gotta remember the valves are custom as no one makes a shelf valve for these from what I remember. A tricked out set...probably 8500 assembled would be my guess.

I'm going to say that the valves are off the shelf. That said, The labor to port these heads will be the single biggest cost. The hardware alone will be no more expensive than what I have invested in my ETP's. So, for those considering them, add anywhere from $2000 to $5000 over what my top end wound up costing. I'm calling Edelbrock tomorrow to get some additional information.

If you were to run these heads I take it you would be looking to run .470-.500" lift lobes?

On a similar build using PI LS7 285 heads, .800 lift.

PAC 1328 springs $400
Xceldyne 8 retainers $377
Xceldyne 8 locks $110
Xceldyne lash caps $200 (titanium valves)

Running 350 seat/ 850 open, the chinese Ti retainers and stamped locks
arn't gonna cut it.

Figure you're gonna run copper intake seats with Ti valves? $400

Pushrods, $140 will get you some 3/8" pushrods .080 wall, would be like a soggy noodle with that vavletrain, you're going to want 3/8 or 7/16" heavy wall pushrods Manley, Trend, Manton, our pushrods for the above build were $500, three pc. 7/16" with tool steel ends. Trend or Manley pushrods .135" wall run $250.

.904" lifters are $750

I'd expect closer to $3000 for a sheetmetal intake

It starts to add up quick.

Even at that titanium valves from del west or xceldyne will run around a 100-110 a piece and 140+ on intakes for hollow stems (n/a applications). I think the overall length on these heads for valves, depending on seat depth etc, would around 6.250 maybe a little taller. Id like to see what Cary's new Moses heads do..
