It seems everyone mostly gets the biggest valve biggest port head they can....but don't you lose velocity at lower lift numbers ...which unless your operating at wide open high rpm most of the time you'd be better off with smaller valves and a smaller port that's ported well instead of huge volume ports with giant valves? I am building a 212 predator billet rod and flywheel with a mamba jr that will see around 6000 rpm at most and I am trying to have good throttle response and power at lower rpms that it will run in most of the time like a street motor vs a drag motor that runs high rpm all the time...what have you guys done for your rides that you don't race high rpm
