Re: '86 manual engine to a '93 automatic truck, what hassles do I have to look forward to?

Good point arse. It would be a good idea to have the old head rebuilt after that many miles. That will also solve the problem of too few exhaust manifold attachment points.

If you decide to switch to a carbed setup retaining the EFI head is not necessary.

Re: '86 manual engine to a '93 automatic truck, what hassles do I have to look forward to?

Nothing major, assuming you want to keep the entire EFI, which I recommend. You'll need to remove and block off the mechanical fuel pump. The head is lacking a couple of bolt bosses so you need to affix the EFI exhausts with two clips to hold them in place. You may have to change valve covers to cle...
