I'm showing the same part number for the cylinder head across the years of '83-'87. (part. no. 944-104-033-06). I think the only difference to the heads over the years is the actual sensors. Someone correct me if I'm wrong. You should be able to take these sensors off of yours and use them on any head during those years.

However, here's an intersting thought;

. . . before you start pulling the heads off fix the crank pulley problem first, then pull all the spark plugs and turn the crank to where the all the pistons are at the middle point of their travel in the cylinder bore.

Once you've done this, see if you can turn the cam one full revolution. If you have a small pen-light you should be able to look into each spark plug hole and see at least part of the intake and exhaust valves as they rise and fall when you turn the cam.

If that all looks good in each cylinder and you don't see any obvious bent valves then try to set your valve timing with the new crank pulley parts in place. (you might have to to turn the cam independent of the crank to keep valves and pistons from hitting.) Just set enough tension on the timing belt to keep it from slipping while turning the engine with the starter.

After you've done this, see if you get a full 2 rotations of the crank (1 full cam rotation of course) without feeling any mechanical interference. If that works and seems fine then squirt just a little oil into each cylinder and do a compression check. If the compression check works out then try adjusting the belts and seeing if it will run. Who knows, you might just get lucky.

Knowing what I know about this engine you'll still probably taking the heads off and fixing valves, but wouldn't it be a slap in the face to take them off first and find out that just by chance nothing bad happened in there!!!!!

BTW, when checking the valves with the with the pen-light you should be able to turn the crank a little and bring a set of pistons (#'s 1 & 4 or 2 & 3) high enough to see their tops to try and check for damages.
