Dart 225s on 408 and Vic Jr
#24
Take a look at the attachment I posted below. This is the best real world flow numbers I have seen on these heads. The chambers on the Dart's are "as cast" unless they have changed. I got mine right after they came out. I don't know how much compression you will gain. I can tell you that mine are milled .020" and I am very pleased with them.

Robert, here's a really good option for you. If you check on ebay you can find all pro bare castings brand new for $750 + shipping. They are an as cast head like the darts, but have CNCed combustion chambers. He includes guides, but they need to be installed and they need a valve job. You can send them out some place, have them install the guides, and give them a nice job for relatively cheap. That way you'd have a really nice head that would flow more than the darts and cost you less. The All Pros have other really nice advantages like :
-3/4 deck
-Dry deck design
-Reinforced rocker pads
-Raised rocker rails
etc... etc...
Check out their site or give Bob there a call. He's really smart and knows a lot about their heads.
EDIT: Picture from the guys add so you can see what I'm talking about.
I bought a set from the guy and I'm going to send them off to Bob at All Pro and have him work some magic on them. I just have to wait until I get my tax return.

Well...The "vendor" problem is not what I am refering to. Dart assembled heads have had quality issues. Some choose to buy them bare to control the issues. I'm not saying ALL the assembled Darts have problems but many have. FWIW Bret Bauer, Bauer Racing Engines will put out a kick *** Dart head.
Out of the box, my Dart 225's made 404rwhp/370rwtq (unlocked) w/ the FM13/112LSA, LS6 intake, .040 cometic, PP stock TB, Mac mids w/ cats, 3600SS stall, 3:73, Dana S60, 315 M'T's on 17x11 TT's and ran the times in my sig. FULL weight + ..
I know of a few people around here that are running the (out of the box) Dart 225's on 408's and are running <10.99 1/4, N/A
I have no plans to ditch my Darts

Here's some info from Basso SA's website that you may find interesting:
"In 2002, it acquired Manley Engine Valves Factory in the United States, which allows the consolidation of its development in the international markets."

I recently installed a set of 225's, but have no numbers yet. I'm finalizing the fuel system so I can install a mamofied FAST 90/90. If you want a very nice set of heads, contact Bret Bauer for some Dart 225's.

I just installed a new 408ci for a customer (Junior) with Dart 225's the Bret worked for me. We should fire it up today and posibly get some dyno #'s late this afternoon or tomarrow.
I also have a set on the way back from him that were on a 410ci vette. It was making 520rwhp with them pretty much outa the box. We're going to drop a point of compression and with Bret's port work we should still pickup hp and trq.
I'll post the reults of both cars if yall are intressed. Both cars have custom cams from Bret also.

I'm looking forward to seeing the results.

I totally forgot about the 408 we're waiting on push rods for. It's just what the thread was asking about. It's a 408 with 225 Darts straight out of the box with the Victor Jr intake a in shop elbow and a custome Bret B cam. The #'s may be a little low looking on it due to the Th350 trans and nitrous converter though. But the Et's should be pretty good. I'll post the #'s on this one also when we get the push rods next week.
If anyone needs prices on the Dart heads just pm me.

Hey buddy how's it going, haven't seen ya around for awhile. Thanks for helping with my tune sometime back. Let us know how things go, very interested. By the way, in my web is a fuel system up grade write-up you may be able to get some insight from.

I wouldn't call the Dart valves 'no name', they are manufactured by Basso SA in Argentina. The valves Dart uses in the LS1 head are equivilant to a Manley severe duty.

Ok I got some dyno #'s today. 482rwhp/435rwtrq
408ci, Dart 225 heads ported by Bret, Custom B-spec cam, Fast 90, ARH headers with cat'ed y pipe to SLP loud mouth cat back, A4 trans with a yank 3600 converter, Dana 60 rear with MT ET drags.
Got a little tuning to go, not sure if the #'s will improve much more though. It's hard to believe how good this engine rev's, it's crisp as heck.
