Default Does anyone have a set of Dart 205's on the bench?

Looking for someone who has access to a set of Dart 205 "as cast" heads. I need some measurements off of them to figure something out I am working on and don't want to pull my intake to get the measurements. Let me know if you are willing to take some vernier measurements and I can send you a sketch of what I need?

Thanks for any help

Thanks but I think the port widths might be different as they are larger. Hopefully someone has a set of 205's laying around.

Hey man, I measured some of the critical dimensions on mine. For instance the bowl was well above 90% of the valve diameter. I recorded all of the dimensions I took. I may or may not have what you're looking for.

What do you want?

First thing I need is the width of the intake port right at the intake manifold. Need a pretty accurate measurement though.

Nope, don't have any of measurements like that. What are you working on? The runner can be a bit wider than the intake.

I am wondering if the "as cast" Dart runner might be a bit on the narrow side.

The runner is small compared to the size of the bowl, but I don't think that's the most effective area to improve upon when porting on these Dart heads.

I am looking more at whether it is a good match to the intake, I have a funny feeling it may be narrow so intake ports may not match well. I just don't want to take mine apart to get the answer, hopefully someone has a set laying around and they can grab a couple of quick measurements.

According to Dart the intake port dimensions are as follows:

205 - 1.020 x 3.170
225 - 1.030 x 3.230 (Verified on my 225's)

Fast intake - 1.015 x 2.685 (Verified on new intake)

All are 'out of the box' measurements

Thanks. I looked on Dart's web site and didn't see any dimensions.

These are on the information sheet that came with my 225's. I don't know whey they don't publish the spec sheet on their website.
