Doug, those are Scott Cooks heads, they have high swirl combustion chambers. They can run 11:1 on the street with pump gas OK. 28 degrees ignition is full advance with those heads!
Corey, comparing two random engines proves nothing. To do a comparison between parts you need to be swapping them on the same short block, changing only one thing at a time, the parts in question, whilst other important things like cams, pistons, carbs remain the same.
You're taking the thread in the wrong direction. My point is admiration of that flat torque curve, not a head comparison. Its OK for me to admire the torque curve of that motor, it doesn't detract from TFS heads in any way. You're welcome to like TFS heads. I don't dislike them. But your post seems quite rude to me. What is your point, what are you trying to accomplish. Do you insinuate nobody should purchase SCM heads?
