Inliners International Forums General Discussion Blown and Injected Lumps needed for low RPM turbo motor?

Late to the party on this one but if you are still curious, you might try to track down Leo Santucci. He had a sissal head that was lumped for a turbo application. The lumps were done in epoxy. There is a photo of that head in his book. Interestingly enough, I currently own that head. He would be the one to ask whether the lumps helped in a turbo application.
