We just left DART oogling over their new LS1 Cylinder Head. They are offering two versions of this head in a 205cc and a 225cc version.

I will have detailed flow information later today.

We will be taking pre-orders for the heads starting tommorrow, quanities are limited so be sure to act right away if you are interested.

Please PM or Call for pricing and availability.

 

Here are the flow numbers for both heads.

Per my source at DART they will be using the Comp 26918 springs, and the first sets will leave them in 2-3 weeks time.

 

I saw an add for them in IIRC Car Craft. Went to their website and they didn't have anything about them at the time though.

Any idea on cost?

 

PM Sent

 

throw me a PM about cost as well...

since they really don't flow like crazy, least not more than most good stg 2 ported heads...
i would hope the cost would be decent

 

Agreed, especially if they only come with the 918 springs. And by decent I'm thinking about $1200 -$1400.

 

agreed...

although the smaller intake volume would be nice for low end grunt

 

They are in that range, you have a PM.

What other heads are people using that are similar to these? How much more are the AFRs?

 

ET Performance and AFR cylinder heads are other options.Both will run you roughly $1,100.00 to $1,500.00 more than the Darts.
