    as I progress getting ready to pull the engine from my 82, getting the nuts off the exhaust headers is really hard. My headers have a shroud around them as a heat shield, which is welded in place, as well as the horrible air injector pipes which block access to the top header bolts. Getting the rear header bolts off was doable with great effort and knuckle scraping. However, I just can’t seem to get to the top row of the front header bolts.
    is it possible to lift the engine with the front header in place? Any suggestions how to get the top row of front header bolts off? I have all kinds of universal joints for my sockets and wrenches and small fingers, but I’m running out of options and patience.

    it would be nice if the front header come out with the engine, but i fear that is not possible

    No possible to lift it with the front header in place. The header actually needs to be left in the engine compartment.

    I find these to be helpful:

    1. Lid off, engine plenum off, starter off, alternator and bracket off
    2. Blanket over the top of the engine, and you laying on the engine. Feel your way around with your hand, and a mirror. Use a number of long, medium, and stubby wrenches
    3. If you are absolutely in a bind, drain the gas, remove the right side gas tank so you can ... tuck yourself into that spot. It gets easier.

    That is the hardest thing to do on this car during the engine removal.

    The air injection tubes just make access to those top bolts so difficult. They are rusty with 1000 sharp edges.. I can’t wait to throw them away after beating them with a sledgehammer.

    I think the sampling tubes are more troublesome.

    Dont disassemble the car. Pull engine half way out then unbolt it and drop it back into engine bay. Easy. Reinstall same way. one person job. Just did it the other day

    if I understand you correctly, you’re suggesting to lift the engine up to access those bolts? That’s what I was hoping to hear. I think that might make it less difficult

    I just did this 10 minutes ago on a 328.

    Remove the starter and the alternator.
    You can access the top 4 nuts from BELOW with a 13mm wrench, and a ratcheting wrench.

    my header has a "sleeve" or shroud around it, making it impossible to get to the upper bolts from below - i am thinking of cutting off this heat shield when i go to put them back in - i like the idea of a heat shield, but access to the nuts is just nuts...

    I just did this with the same headers with heat shields. Access is possible.

    Its easy if you do it the right way and no need to remove alternator and starter.

    ok, so here's my plan:
    1. leave alternator and starter in place
    2. strap around front head, going below header
    3. lift engine a good bit - secretly pray that everyone is wrong and front header can come out with engine, but knowing that wont be the case
    4. remove top 4 header bolts, trying not to scrape knuckles on horrible air injector plumbing
    5. lower engine down to release front heaer
    6. lift engine up (pray that i have enough clearance to ceiling)
    7. remove engine

    I just put my engine back in, and I just used one box end wrench for every single nut on both headers so it can be done, but I do have a hoist and some I did from the bottom and some from the top. Alternator, starter and motor mounts in place. It would have been easier using a combination of different wrenches and sockets, I just wanted the challenge. However I also have the sampling tubes and air injection nozzles removed and plugs in all of them. I'm writing this less to try and make it sound easy, but more as encouragement and that you can do it, especially if you do the extra things people are suggesting.

    Strap goes around intake cam for proper angle. Not entire head.
    Why lower engine to take off header? Who said to do that? Get it high enough to reach upper row of fasteners, unbolt it and take it off
    Why make this complicated?

    The main purpose of those shrouds is to retain exhaust heat for the catalytic converters. You can cut them off (I did) but my Lord it is a real chore, they don't come off willingly and they will never be useful for anything again once you're finished.

    While it is a primary purpose they have the benefit of keeping the engine bay cooler and in the case of the front one reduces heat radiated onto the firewall between the cabin and engine bay. I never consider removal.

    For 47 years I have worked on Ferraris for money. Time is money, mine and the clients. I do everything the easy fast way and engine disassembly is more quickly performed out of the car. Having the induction system off in no way makes removal easier.
