So perhaps Im incorrect, but I get the sense that many think this mod is a waste of time? OR is it that what might be gained doesn't justify the cost?
So anyone who has BTDT willing to offer what EMW, Len (when he was willing to do this work) or FAT charged to twin plug a set of heads ? A related but important question is, along with simply drilling for the plugs, was that the extent of the service? Or is there always a degree of unshrouding /porting that makes the application viable? |
