are the XUD11 pistons the same height as XUD9? and the pin size the same?
tbh with the minimal difference in price these days I'd just run a HDI, theyr'e better on fuel as well.
I get free waste vegetable oil , and already runing a 406 xud9 on wvo.Xud11 pistons have a longer stroke but not by much.

If i take it on his words, my main concern is fitting the xud9 bosch pump due to the dowels and bolt holes being different.
There are some folks in france who run the 8v xud9 head on a xud11 engine , so the xud11 pistons shouldn't make trouble with 8v head. The question is what crank shaft should i use with a dw10 block, xud11 pistons and xud9 8valve head? dw10 crank shaft/ xud11 crank shaft/ xud9 crank shaft ?
