Default Head flow questions
What % of cfm can the intake flow over the exhaust?

Say my intakes would flow 365 and the ex. would flow 275 would this be a problem?

They are usually between 75-80% The higher you get the more likely you are to see a cam with a single pattern. Whereas, the lower percentage aids the exhaust with a split pattern.
