Its not really all that bad, just be patience ansd have an a/noon free....undo your motor mounts so you can lift the motor some...the pass side was the harder for me...it just took some snaking around...use a 2x4 block under the front oil pan to lift the motor...i did the drivers side then lifted the motor, pushed it over to the drivers side, snaked the header in...I even left the starter in to boot..
the drivers side falls in easy from the top...youll need to undo the steering shaft...make a mark on that so you line it back up the same way...
your dipstick may be an issue to...with my Mac LTs it worked, but had to be swung off to the side of the fender...I bought a curved Fox dipstick out of FRPP and it worked like stock...snaked thru the tubes and bolted right back to the stock header bolt...
I would suggest some stg8 lockers to... mine haven't leaked or lossened in 4 yrs with them an 1415 Fel-Pro gaskets...
I would also suggest a AFPR if your not running one...mine was pig rich after the install...I dialed the fuel down some to start and then dialed it back up a few lbs at a time doing plug checks...its a poor mans dyno tune...but it will work...mine was puking Black smoke after the install so I knew something was up..
O/2 extensions to...either add on to your or buy em...
