    Those things are killer. I love those heads. For the money, for a 23 degree low port head, they make serious power, worked up properly. Even just mildly done, they will make good power.

    They do use an off-set rocker though, which is one of the advantages of them. I wouln't buy complete heads, from a certain big mail order house in Wisconsin though. Trust me. If you want .010 run out valve seats, and cheap parts, then fine.

    I like them better than AFR for sure. Dart makes some nice stuff. The thing you need to realize, AFR has to CNC their heads to make them even work ok. These, bowl blended and port matched even, will make some pretty serious power. I guess, when you say, how do they compare, what do you mean? And, compare to what? I mean, they have some features, the others don;t. Like power vs power?

    I haven't used the Canfields, but I know a few that could not get them to work well, could have been the combo's they had. If I was in the market for new 23* heads, Darts castings are the finest and you can get their non-CNC to work well with minimal work. AFR CNC's their heads as a standard practice and also work well. Just remember when you look at the larger runner heads you have to go to offset shaft rockers. What is your 408 going in and what is your ET goal? Or street? Let me know all the rest of the parts you plan to use, trans, converter, gear ratio, vehicle weight.

    Then reason for asking is that the # of SB heads out there gives you a lot of choices. Whether you want them for a 15mpg, 15 second street car or an 8 second dragster does come into play as to your choice. If your looking for non-CNC'ed heads, Dart is my favorite. They run well with very little port clean-up. The material, casting quality and machine quality are as good as it gets. For the price, there is no better. You can get them from 180cc to 230 cc depending on your combination needs. For CNC'ed heads, AFR edge them a little. You pay more for them. Canfields like all others will run and can be made to work OK, it just depends on you goals and combination to go with it, and how much you want to spend.

    I have two sbc 406 engines with these heads(220). Make sure to use the stud girdle and offset rockers. They make very good power. Mine have the 2.10 intake and 1.6 ex valves. Aligning the rockers to the valves is a little tricky but easy to do. The correct pushrod length is very important. John @ Canfield is very helpful.
