Dart Heads
They flow 320 cfm on the intake side and 224 cfm on the exhaust @ .500 lift.
That is 51cfm and 46cfm over stock.

I wanna see someone use this on a bored/stroked B20

Honda Tuning used the Dart block and Head for a B20 Vtec motor. The thing is a beast something like 315HP N/A. Lemme find the article real quick.

A well worked OEM Casting cylinder head with proper porting and cams will make the exact same power ...

The extra $$$ spent on a DART cylinder head would be well spent somewhere else ... After seeing both I belive the OEM unit has better fit a finish and smoother castings than the DART product anyway

I tuned a vehicle using a Dart cylinder head. All I can say is the motor dropped a valve within 7 days using Dart's valvetrain. I don't know if the issue had to do with the kid not knowing how to drive or if it was a failure in the head. I was not very impressed with the hp gains made by using the head over a traditional head, however it was only a 1.8L n/a setup using mild compression & a crappy GSR DC sports header & restrictive exhaust system.

Yea the entire motor was deburred by hand and everything was done perfectly. From my estimate there is close to $10k into the motor not including the cost of labor.

It has custom ground cams, the combustion chambers have been welded and redesigned, nothing is even close to stock. The block is a sleeved close deck design by Dart and they use custom pistons as well. The motor is pretty much a one off thing.

...but, in an extensive build, i believe it would make a difference.
