at least 6" for the 2x4 and probably 8-10" for the single 4 top.

you mean C460 cast single 4 to a A460 with Single 4 top .. about 4.6 inch taller . then add what the spacers add to the hieght when TR is used with C460 heads . note: spacers and gasket total thicknees will add a little less height than total
