really, the best thing is to put it on a degree wheel, and find out what the timings are at......i think the stock exhaust may be 31-32mm to the top, but don't care to find the rest of the measurements

Not 100% sure but if I remember right the stock transfers are something like 43-44mm from the deck, and if they are something like 41.5 to 42mm from the deck they should be around 127 to 130 duration.

I think you should measure them first and post your numbers here.
