Is it going to be a big cube engine with the ability to rev 6k+...I ask because those heads have a 210cc intake runner.
They also want you to use shaft mounted rockers...big $$$.
They look like a nice head and I like that you can get them in 3 different stages.

 

Its going to be a supercharged 355. I am not using shaft mounted rockers, just offset ones for the the bigger runners. These heads are made using plastic cast, the runners are very smooth, much cleaner than even cnc AFRs. Im getting them bare and putting together my own components.
