Hi Mike,

You didn't give any dimensions which makes it a bit hard to know just
what oversize you need. Denis Welsh has exhaust valves for the BN2 in
1.562" & in 1.614". I think it is fairly common to use the AH3000 size
(1.562") exhaust valves in the four. Maybe standard AH3000 exhaust
valves will work? Don't know about the stem length & diameter.  My DW
aluminum head came with the OS valves already installed & I didn't
bother to measure anything. Maybe someone can fill in the gaps in this info.
