Dart331 is refering to the factory rocker assembley as "a shaft type" since it is not a conventional stand alone stud type. Yes a true T&D or Jesel would be great - but it is not a must have to work on a Dart head.

What about the Yella Terra rocker arms..are there any issuse using them on the Dart heads..ie. what would you have to do to get them to fit??
For those asking about the rocker stand for the stock rockers, it will take two minutes to fix. I felt obligated to post this since I think I first brought it up. I think the other thing to consider is the LPE steel stand as a nice upgrade, but anyhow here is what needs to be removed. It is the little locating nubs on the bottom (circled in red). You can see in the photo that the rocker support bosses on the Dart head are larger and more robust than the stock head, hence the need to remove the nub.
PS: The heads are not blue, that is painters tape to protect the gasket surfaces while I work on the heads

Just got my test set running today in the car... just did a warm up shake down run in the car. Freezing rain is preventing any test drives. I thought the car wasn't even going to drive or idle with the cam in it but it turned out it was fine on the stock tune too.... I'll finish the car up this week and hopefully we can dyno this pig by the end of the month maybe!

I'm by no means discrediting the facts of this head.
Just from my user point of vue (as a lot of us do their own work on our rides), making the head more simple bolt on, (more PnP) if you wish, is what a lot of us would prefer (I know I do).
As Cast, professionals like yourself or SStrokerAce do not have any issues sorting out details, for us however, the lack of tooling resources can sometimes involve extra costs that we would rather not have.
As mentionned above, quite a few consumers would look at this head a good product that is also "well Budgeted".
That is what I was trying to say.
We all seek "MORE POWER", but we hurt trying to do so within a reasonable amount of $$$.
It was just some input that is all, I personaly gotta wait for more LIVE data to make any judgement so do not take those comments as such.
BTW: Do you have the spring specs?

I got the set here bare.... they were also the first run and they needed a little work. Dart has fixed the areas that I had to fix on the as cast heads from what I hear so it shouldn't be a problem for most guys to just bolt them on now.

Very nice write up. I know when Allan did my heads over a Futral's Terry went over with me all the stuff that people were talking about on the forums. He pointed out and explained what people were saying on the forum about the rockers, oil holding in the head, parts issues. It was very informative to me since this post was not available at the time.

So does that mean these wold be great heads for a forced induction setup? Im looking to go turbo and in the early learning stages of what parts are better for one thing or another. That statement just screams these heads will love boost to me though? Or did i completely misunderstand that?

glad to hear from DART331. i was on the fence about these heads vs two other more $$ pairs and am sure that ill be getting the Darts. after reading his posts though i think im gonna wait and see what the deal is on there forthcoming cnc'd sets.
I hope you get your cnc out by june. I got a rather healthy bomus check I need somebody to take care of for me if you know what I mean. oh well I can wait a little longer if need be because I'm not ripping apart my motor until it's cold out agian.
btw nice post. I like to see people that are willing to tell as it is and not what they hink you should or want to hear. some other people on this forum might have gotten a bad rap for doing do but they have alway's gotten my business. thank's for the good work.

Sorry to dig this thread back up but I need this question answered. I have the as cast 225 Darts & I have purchased the Yella Terra Ultralite Shaft Mounted Rockers. Are there any issues that anyone knows about? Anyone have any idea on pushrod length, shim height? I would rather not buy some more pushrods but I will if need be. Thanks for any answers you can give me, and thank you Dart for a great head!
