Reply to "Wide and Flat Torque Curve"

I think its great Scott and Darin brought another head to the market, but I did't think Corey was out of line or rude to make comparisons. I mean how can you say something is an improvement or not unless you have something to compare it to? Its really hard to make apples to apples comparisons considering all the variables that go into building an engine and what kind of performance and operating characteristics you are willing to sacrifice for, but if someone is looking at buying a new set of heads, they should know whats out there and what people have been able to build. There are a lot of cleveland heads on the market, so its nice to be able to critique the benefits/drawbacks of each one, think that is what these forums are for aside from keyboard racing The fact is there is no one best head choice for every build.

To me this head appears to be competing at the top of the street offerings arena from TFS/Ebrock/CHI/AFD since it retains factory header/intake style locations vs high port offerings, probably more with the CHI versions since it has CNC work done. Even the intake/heads Scott mentioned that he tried to retain the look of the factory heads/intake in the external castings. I think that is great if you are out grudge racing people and trying to pull the wool over someone or just want your factory street car to retain that appearance. Hell I'd paint the stuff blue haha. Seems like most folks advocate a 225cc head minimum for a windsor or cleveland stroker, so I don't see how this head would be too large.

I think doug brought up a good point though, these dual plane strokers done right make a ton of torque which is not exactly what any transmission including the ZF want for longetivity. I'm honestly baffled to see dual planes on 400" strokers given the ZF's limitations. That and a 400" engine wants to breath! I get most of the builds here are for people who want streetable performance, but my belief is the single plane gets an unfair reputation of being a race only piece. I really feel this is a huge misconception especially when you get into the stroker small blocks which can pull a ton of air from a common plenum. I also get the argument is that lowering the powerband can make it more usable for a streetcar with more reliable performance because of less strain on the valvetrain and a powerband more suited for a street car. Not sure how you are going to plant 500+ ft lbs of torque on the street without pedaling the skis though. Are we doing this for bragging rights? I thought the whole history of the cleveland was to wind them up with the large port heads, and that is what made them shine over every other small block. Might as well stick a dumptruck windsor in the thing if you just want to rev it to 5500. No offense to the windsor folks
