heads

ps ..the W2 and W5 heads make killer heads..
i have no experience rpm eddies..
but i have a set of large commandos
the architecture seems good dont know how well the machine
work is..as i havent blue printed them ..
but should be a good performance head..good ports.high guides
nice exhaust shape..the flow in the 250 range out of the box..
i think bobby flowed them out of the box? he might have numbers.
i know side by side on the same bench they flowed more...(memory?)
