While we're on the subject here's the flow chart for the Profiler 12 degree heads (big chief, spread port etc.). For comparison, a Brodix 3X CNC flows 416/290 @ 0.700".

Just wondering what everyone elses experiences have been.
That 700incher need alot of air. smaller inch engines do not require that much air til they get in the upper RPM's , but there is alot more sience to it , alot of different opinion's and theroy's ,,,,, also when talking supercharging every thing changes slightly larger heads are more efficient, also diferrent theories

I talked to Mark about Too Old's motors and he said to get their hp it took alot of work on those profilers, definatly not out of the box.
