The real ***** is the drivers side header with steering linkage removal (or semi removal) and ground clerance when sliding them in. Gettin that car/engine up high enuff is a PITA.
oh yeah, i forgot the steering linkage, but it went right through. had to lift the engine up about 2 or 3 inches with the cherry picker on the passenger side header. dropped right in, didnt even have to lift it up any for the driver side, just had to get the steerign link through it. 5 and 7 cylinders are kind of a pain for changing plugs and burning plug wire boots.
