    Woe I feel like a real dumb ***. I just see under my last post that I had in fact already answered your question. Woops.

    Hey man, I just now saw your visitor message you left...yeah it can be done they make a stepped dowel pin. None of that matters so much...all that really matters is that you have .035" or more of clearance from the injectkr clamp to the rocker box. The trouble is that they actually made 2 versions of the 20mm heads, there were 2 different rocker box dowel pin locations, the earlier 20mm heads will take the same rocker box as 18 mm heads the later model uses a rocker box with dowel pins in a different location, which will work if you use the right rocker boxes. If the 20mm heads have 10mm threads around the perimeter of the rocker box bolts, 2 of them I believe then it takes the later style rocker box. If the bolt holes on top of the hesd where the rocker box bolts down to is 8mm threads (2-3 along the side nearest the intake ports) then it'll take the same rocker box as 18mm dowel heads.

    It will bolt on, they make a stepped dowell pin, that converts 18-20, but the injector hold downs are different. Injectors are the same, so as long as you swapped out the hold downs you'd be ok, and the appropriate gaskets and dowel pins. Good luck.
