Let me say I'm currently running Dart Pro One 200cc heads on my motor and making good power. However I'm in the process of building up a new motor for more power and higher rpm and I'm going with the Dart SHP block and the AFR 195cc Competition port heads.

One of the reasons for the AFR selection besides the better combustion chamber design and flow numbers is the light weight valves and springs for higher rpm without valve float. I estimate my new shift points to be around 7000rpm.

I run Dart products and would buy them again but I feel at this point in time AFR has a better product. Simple as that.

I pretty much agree..... I ran Dart cylinder heads for over 7 years before switching to AFR's, I won most of the below trophies with the Dart's, those are not just bracket racing trophies, but also late model Heads-up shoot-out event wins as well. I never had a single problem with them.... I then did the same test that Wes did, except my test was on the dragstrip instead of the dyno.... I went over 2 tenths quicker with the AFR's without any other changes at all..... but that doesn't make me hate the Darts. I had a great time with them, but I do regret not switching earlier, might have been a few more wins if I had.
