Both heads were the same price last week. I think that there may be a price increase on both, not just the 225's. May be due to changing over from the SBC valves, etc. I don't know for sure.
1) Why the smaller diameter valve guides? We decided the smaller diameter guide allowed for us to shrink guide boss. We did this because testing the heads with the ported models we used to develop the as cast ports the fuel and air stream when tested on the wet flow bench showed favorable results, so we use the smaller guides.
2) Why no thread inserts? At Dart we strive to use only Pure Virgin Ingit 355 alloy, this material by design is stronger, more repairable, denser, and has less elongation than 356 often used by the competition.
3) Why no steel inserts where the heads bolt holes are? Same as above answer really, when using a material that is superior in strength, has more tolerance to distortion and failure there is no need to "band aid" a problem.
4) What do you do with the area behind the seats? We blend the bowls in every aluminum Pro 1 heads we make, and also the LS heads, this has been our standard for years. This eliminates the edges that are commonly found that can have some affect on the heads.
Thanks

Wonderful, so why haven't we seen more awesome results, or even any results?
The bulk of our shipment began the last week of November, many people are just now recieving their orders. As far as results - check the post by Kurt Urban on this forum titled "dart as cast test" where the Dart as cast head is compared apples to apples to one of the fully cnc'd heads that many on this board rave about.
Also Bret Bauer has done some playing around with some of the early castings of these heads - look for his post as well.

At 80 sets a week, just hoping to see MORE results.
They are beehive and similar to the 918's.
I heard they are good to .650 lift. Is this correct? I thought .600 was it and how about RPM's with a hydraulic cam and stock type lifters.
