    Well to put it into context it flows 1 and 1/2 times the amount of air that the current head does so could make near enough 300bhp.

    theres not an x/flow head in the world that could flow that much air.

    looking at the numbers and valves sizes its a multivalve, imperial valve sizes suggest something old

    BDG, with injection instead of carbs you come close to 300 BHP these days (doesn't last long but ...)

    Re: Cylinder head flow chart.

    What is the flow depression? the flow figures are pretty meaningless without it

    Did I just hear 300bhp and xflow in the same sentence lol

    If those flow figures are @10" which it looks like they are, then it has to be northing other than a BDG or BDX 16V head, yes I see there are 2 in & ex valves in the spec sheet

    The inlet to exhaust flow bias is very good

    Yes the flow is @ 10" water
