my wr 400 has eaten its own big end and i'm thinking of doing the old bore out job on it. i have seen a few threads on here about doing the 426 conversion, but having seen 98mm big bore piston kits for sale for the 450 i have decided to have a go at somthing different.
i was wondering if any one knows the valve sizes of the 450 head compared to the 426 and 400, or were i could get this information.

does that mean i can't fit a 450 head on a 426 cylinder?
