We use them at our shop quite a bit for the past 5 years or so and have very good results.

A 383 making 490-ish RWHP. 427 at 500+RWHP, basic LS1 heads/cam packages at 425RWHP with a 224/224 XE, Z06 with a basic heads/cam at 445RWHP with a 226/230 XER and so on.

A lot of folks will say that these are average numbers and that is my point. In a similar combination, the CNC heads will run with the best of them. Flow numbers and port volumes in the range of the AFR's for the most part.

They do not "pretty" them up as some shops do, so you will get the "does not look as good as the X brand head", but they do what is needed and it works. Of course there will be several opinion on this to say the least. Hope this helps.

FWIW- I called the shop once and they are very knowledgeable and helpful and are a big, well funded shop (helps with R&D). I wouldn't hesitate to buy heads from them.

Thanks. I was told that they have AFR performance without the AFR price premium.

I have been running CNC LS6 heads for about 2 years and I am very pleased with the results. In my 2000 C5 346 A4 I ran 11.07@123.87.
