Like I said DanL, the numbers for the Dart are close, certainly not better than the Canfield out of the box. I have had Dart 320's and Dart 360's, and they are great heads, I currently own EPD ported Brodix heads, and a brand new set of Canfield 350 cc runner heads, I'm certainly not running Dart heads in to the ground(water). Some where along the line Dart's were the new kid on the block, we have come to know and love them. All that I am doing is giving Canfield a good chance by buying their product based on the fact of successful motor combos of friends and colleagues. Further the Canfield are available in several different chamber volumes, it is your choice, and you can get them factory CNC'd.

I have flow benched all the major after market heads and to date only Canfield and Brodex have flowed per their adds. The rest were blowing smoke or flowing core boxes not castings. Doing a set of the new world bbc right now ... real tests not mfg adds. If any one is interested in the results or results for other heads we have done let me know. The Canfields simply give the most flow for the port volume also there numbers will keep going up till you go through a port wall. All others go turbulent before that happens.

Hey Cigarette 39 I'll get you that camshaft profile for the 605, I think the guy is leaving for Daytona Bike Week, I'll see if I can get him before he takes off.

I bought two sets last winter. I am extremly happy with them. I bought the 310 runners, the 113 chambers. The Canfield tech rep lives about ten minutes from my house(I found this out when I was ordering them) He gave me a # for one of his dist. and said he would probably give me the best price.

JimV flowed my Dart aluminum 310 PRO-1 heads right out of the box and was practically ashamed to let me see the numbers. He said what Dart was advertising and what they actually flowed were not accurate. Fully ported or even mildly ported they seem to be a good head...he got them working pretty well for me, but out of the box you won't see much difference. Testing was done @28" of water.
I know some guys who went from GM rectangle port heads to the out-of-the-box Dart 310 Pro-1's and saw no increase on the dyno or in their boats. Needless to say, for the high expectations that they had and the money they spent, they were pretty disappointed with the final results.

Also machine work on the afore mentioned heads are is superior to the competitors.we are flowing aset of Canfields and a set of factory ported Pro 1s right now asa study results I willpublish here soon.
