I plan to remove mine(heads/intake) when I do a major tune up this winter. I have heard that cleaning them(intake) out with oven cleaner is a good idea but why not port them while I am at it? I have a little experience with my Drag bike head. Any suggestions? What about extrude honing the intake? Just looking for a little easy gain while it is apart anyway, don't want to spend a whole lot though.
