here's the flow data on the heads I recieved from Patriot:
dura - intake - exhaust
.100 -- 71.4 -- 59.1
.200 - 146.1 - 118.1
.300 - 212.5 - 159.7
.400 - 250.3 - 190.9
.500 - 280.7 - 206.7
.550 - 291.2 - 214.2
.600 - 299.8 - 219.2
slightly less at the very top on the intake side, my exhaust side flows a bit better than the flow chat on page 1. but the point of my comparison is that the numbers are VERY close and are repeatable, so what you see in the flow chart Gunnar posted is very close to what you'll get. the 227 CC intake runner is not a hogged out runner so low end/mid range should not be lost. good customer service as well.
