Any one here run the dart 205 heads?
If so how well do they worked unported? Im looking for a good replacement for my stock ls6 heads and I have a 231/237 585/595 cam. Any issues with them?

I researched this a few years ago before I bought heads and ended up buying the 225's instead. From what I recall, there is no loss in torque with the 225's and they flow a little better overall. And if you ever want to go with larger cubes you can have them ported and they will be some of the best flowing heads out there if the right person does the work. The downside is they have a few potential quality issues. I think my set has a few loose valve guides because last time I changed plugs a few of them were oily. This is not an uncommon problem.
If I were to do it over again I think I would purchase something else. There are better flowing heads for the money today.

I have heard that before(didn't seem right) and so I looked into it.
Here is what I came up with.
Stock Ls6 heads...intake @ 0.500 flow 260 exhaust @ 0.500 flow 169
GMPP CNC'd LS6 heads intake @ 0.500 flow 290 exhaust @ 0.500 210
Dart 205's....intake @ 0.500 flow 290 exhaust @ 0.500 flow 205.
You decide...
btw AFR 205's intake 281 /ex 221. @ 0.500

One thing I have learned is that you can't always go by the advertised flow numbers.

2001 LS6 didn't have the lightweight valves. I ran the Dart 205's for two years and have since upgraded to AFR 205's. Personally, I would look at other heads. Reports I have gotten from some builders is that the Dart's are having issues with quality (too much clearance in the valve guides, valves not centered on the seat, etc.). Mine were one of the first set of heads they made and I had no issues, but there seems to be a lot of problems now from what I have been told.

I looked into the dart heads a few years back when they first started makeing the heads for the ls1 and found out that on a lot of their heads they were have problems with the valve seal. From what I have read recently they fixed these issuse not to long after they were first released. I heard before they caused an oil consumption problem because of the valve seals. I bought a set of new as cast bare dart 205 heads from a member on here for $660 shipped so if they will make more power than my 2001 ls6 heads I will be happy. I just can't see putting $2000 plus iin a set of afrs. Before I do that I will build another ls3 headed 408 and let it eat.

Gm tech had a big head vs head story not too long ago. The top heads were trick flow,then afr heads were very close. dart heads were not as good as livernoise cnc ported heads. I had AFR heads and they do their job. if money is not an issue then the trick flow 215 head is a killer piece. my boy has them on a 383ci and makes numbers better then most 402ci on this site. The car pulls like mad too.

I bought my Darts bare for about $600. I can do a valve job,porting,etc... and save a lot of money over a $2300 set of AFR's.I got nothing against AFR's other than the price.
I was actually going to buy a set of $1500 PRC stage 2.5 LS6's before I bought these Darts. Just can't beat the price when you're on a budget.
