Default Problem w/ Dart Heads

Bolted on a set of Dart Iron Eagle heads(200cc intake, 72cc chamber) to my 383, and when I went to put on the intake, noticed none of the ports line up with the gasket! The problem is on both heads, though one is noticably worse than the other. The bolt holes are in the right place, but it looks like an issue with core shift from the foundry. The same gasket(Fel-Pro 1205) fits my RPM Air-Gap perfectly however.
Summit has already said to send them back for another set(they'll even refund the shipping charge ), but now I'm a little reluctant to do that for fear of getting the next two off the shelf with the same problem, and I'm now seriously thinking of trading them for an aluminum set with similar specs(except with a 64cc chamber)

Anyone run into this problem with Dart products? The head# is DRT-10421112P if anyone else has them.

Any suggestions on a different head?

Thanx

Default Sorry to hear of the setback.

But really its better you caught now than struggling with it leaking.

Yea 682XLR8, i think your right not to test the Dart products again. Don't you really want aluminum to lighten up the front almost 50lbs?
As for other heads i think the TrickFlows are the best value. Also Racing Head Service (Comp Cams) is back in bussiness with modern sb heads in a varity of sizes.

Good luck and hope u get it worked out - that roller stroker gonn'a be a killer.

Yeah, the Trick Flows were my first choice when I first started thinking about building this motor, but they only sell angle plug heads, so my Hooker comps wont fit It's always something!

Racing Head service, I've heard of them. Are they a division of Comp Cams? Im gonna look them up

Thanks for the tip

I bought a set of Dart Iron Eagle 180 cc / 72 cc heads several months ago and they were perfect; plug and play. Effortless fit and great performance. I was very surprised to hear of this problem, I would call their tech line. God bless, Sensei

Can't remember the # of the TF heads, but neither the techs at Hooker or Trick Flow would garantee a fit, in fact Hooker footnotes say angle plugs will not fit the Comp header(not super comp, yeah, I know, onceagain I cheaped out and it's come back to haunt me! )

Well, this is the first time I've heard about problems with Dart heads.

They're known for their good quality!

Core shifts will happen once in a while when casting.
Quality control at Dart might have missed this because they most likely only do sample testing. You simply cannot inspect every head if you produce a lot of them....
So you check a few samples out of a batch, and assume that the rest is ok.
This is normal procedure for manufacturing companies!

I would not be hesitant to buy a set again.
If summit sends you a faulty set once again, they have a problem with customer care!
And if they refund the shipping or do everything free of charge, why not give it a go!

I'm running the Trick Flows and the comp headers on my '71. There is no problem at all with fit.

Dart quality is one of the main reasons I went with them. I've never heard anything bad about them either, until now!

After some thinking, I think I'll try them out again, partly because I know I have all the right valvetrain parts for this particular set-up, plus I know a good set will do what I want them to do.
So thanks for all the posts everyone! The heads are already boxed up and ready to ship back to Summit after work. I'll post again when the second set comes in

I 've had my Hooker super comps 1 3/4 headers for something like 16 years now. I've had not problems with any angle plug heads including my two Dart Pro 1 heads. My 4 kinds of angle plug heads were Chevy, Brodix, Dart 215 and dart 227cc they all worked fine.

The first time I ever had a problem was with AFR 210 angle plugs.

The simple fix is to cut the flange of the primaries and weld in an additional 1/2 to 3/4's of inch of pipe to each primary tube. This also only on one of the headers - passenger side. Then you have lots of plug and wire boot room.

Got a question. What intake gasket number/size is recommended for the DART 200cc heads vs. your Edelbrock Performer RPM Air-Gap intake? Same?

Fel-Pro 1205. It's a print-o-seal (is that right?) type with larger port openings than a regular gasket, and specifically made for sealing against aluminum.
