Not sure of the prior experience of the guys that have already commented, except for DSmuts.
Here's the super simple Bill method:
Remove airbox tube out.
Loosen the crossover bolts 1/2 turn each until loose. This backs them off equally and gives you a 95% chance of pulling them w/o any issues.
Remove both dog bones
Remove 13mm nut for oil dipstick tube, wiggle and remove tube.
Remove the bolts holding the middle of the manifold.
Remove the two nuts holding the ends of the manifold
Take manifold off
Remove factory gasket
Wipe factory gasket clean with a nice rag and brake cleaner
Wipe head surface
Reinstall factory MLS gasket on studs
Wipe surface of PLOG that will mate to gasket with brake cleaner
Look down and note where dipstick tube needs to go when installing, this is a great chance to see the location.
Install plog and all the bolts that hold it to the head.
Reinstall dipstick (sometimes having someone underneath and using the dipstick inserted into the tube helps guide it.
Reinstall dipstick retaining nut
Bolt crossover to plog
Reinstall air tube.
If you think you need heat to do the job. Skip the torch, skip the shop, skip all the silly steps mentioned. Before you start the job, start the engine and let it get some temperature in it. Shut it off and loosen the bolts you are worried about, magical isn't it?
I've had two bolts snap in heads out of a few thousand, it's rare if you hold the ratchet/socket straight and don't turn it the wrong way.
