I have often found it difficult to install the exhaust pipes without having some mismatch in the holes that leads to stipping the threads out. The secret I discovered is to disconnect the other end of the left and right exhaust pipes from the fitting where the two pipes come together. This gives you another degree of freedom to line up the exhaust pipes on the head and get the bolts/studs in without stress. Connecting the other ends of the exhaust pipe back to the fitting can then be a challenge, but if you can safely use a little more persuasion on that end without damaging anything. ***** John Clavin | jjc@bga.com | Austin, TX *************************** |
