Response to im sure someone will beat me to it

the 39x was the first place I thought off too......

But I cant visualize what to do with the exhaoust valve spring (ok I can, it rides on the top or the oring screw)... seems to me though the addition/inclusion of the DORCV will have a ripple effect on the rest of the vavle that'll have to be dealt with.
