what are some tips on how to get the headers off of my truck
But some "Kroil" which is some good penetrating liquid (ebay has some) and let it sit for awhile. Bring the engine up to operating temperature, and use a six-point socket or wrench, or you use an impact gun if you have one. Upon installation use some anti-seize compound on your bolt threads.
there is a spray i ike to use it says pb and is very good for that
your stock manifolds are leaking ill assume and DONT start the engine youll need to spray them do it for a week and then try and break them loose if they dont come loose easiest way is a torch or heat go right through your wheel wells to the manifolds
