    I still can't believe they haven't closed the deck in all these years, but I suppose its not a big deal until you start hitting big boost... But, I wonder if it would prevent some HG issues anyway?

    thanks. so does the cam ride on the saddles on the top or in the holes in the head. also the cam only has 3 lobes per cylinder? is it a system with roller finger followers or rocker arms or what? EDIT i found a picture with the rocker arms on and that is some funky valvetrain with that one lobe and rockerarm actuating 2 valves and the 2 other valves having thier own arms and lobes. this is the first engine ive seen set up like that. one more ? though. whats that second shaft in the block that runs off the main crank do?
