I'm considering replacing my standard log exhaust with ram air. What is the liklyhood of
breaking a bolt? Should I heat up the motor or keep it cold? Any other pointers would be helpful. Thank you, Matt 1969 GTO std 4sp |

Matt there is a lot of stuff in the archives on this subject. I did mine and had no problems. Use a 14mm 6 sided socket on the bolt heads unless they are in brand new shape. I sprayed the bolts with PB Blaster on and off for a few days before I started. I also cranked the car during this time hoping to help work the penetrant in. Just enough to <span class="ev_code_RED">heat</span> the manifolds a little. If you break one, pray it breaks flush with the manifold. Take the rest loose and you'll still have a little to work with. If it breaks flush with the head, post a thread on head removal.
 It may help to take one motor mount loose and jack up that side for extra access. Watch your fingers. Search the archives on topics such as this, there is an amazing treasure of info in there. Good luck, you'll love the Ram Air manifolds. If you have A/C, you'll want to get it out of the way.

Matt,
Go for a drive, warm the engine to operating temp. When you get home, spray the manifold bolts with penetrating oil, it will smoke, but don't worry too much. Let the engine cool for 1-2 hours, then spray the bolts again. The next morning, put your wrench on the bolts and go to town. I did this with 34 year installed bolts, and had no problem. Good luck!
