I have done 6 to 8 and some 17s also , he is correct about the heat . save all original bolts , they are important in restoration , to get the gallon selector rod free , you will also need to remove the packing nuts , they do not take heat and will melt or distort .be careful not to damage the nuts ,I think they are cast aluminum , I used( freeze spray in a can ),the packing is a rope material , hard to save . I just pull it out , be careful on re assembly , easy to scratch base putting skins on , I can give you some tips just call Jay 303-697-0393
