Header install
Just a note if by some chance you are hesitant of a DIYS install, Its not bad, Fun actually, I got my pass side manifold off in about 2 hrs. Im not done yet but it looks pretty positive.
Well I got the drivers side off little more of a PITA but its not bad. 2 1/2 hrs. Hints, Heat shields of the passenger side stay on. Dont waste time loosening. Drivers side heat shield screws need to come out (PITA) shields can stay on. Unbolt engine and lift about 1 1/2 inch, I Kept exhaust connected until that side was unbolted, kept everything from binding.. Most stock manifold bolts both sides are removed from the side. Easy Money. Dont rush get pissed- drop it for the day. Wait untill you see the choke points on the stock manifolds.  Time saving tools- 8mm flexhead stubby, long 15mm offset boxend, 10mm long flexhead. 10mm and 8mm swivel sockets. Thats really about it, Just 3/8 general ratchet stuff.

No rush here just works until it gets hot. The exhaust should connect up with some adapters (3" band clamps). I prepared for the worst and got a mig welder set up and I will make whatever is needed.
