Two races ago, the NHRA confiscated heads from the leading Top Fuel and Funny Car teams to check against the initial submitted parts for approval. Word comes to us that three of the Buell Pro Stock Bike teams had heads taken by the NHRA technical department, and according to one of the teams, the heads might not be back in time for the next two events. Thus far this season, the Buell teams have qualified No. 1 at both events but on race day remain winless.
