the Quest for a Good Head, not what you're thinking Options

My dilemma is that I have a '94 GT, but the motor has been replaced and I believe it to be a 5sfe from a 98+ Camry because of the clutch cover was modified to fit the slight different oil pan.
And my plan is to get a used head and send it to the machine shop ahead of time, but I have to be careful to get a compatible head. And the right head gasket kit for it.
And you guys have got me half-convinced that I could do it myself because in a couple More weeks I will be off for several weeks and could take my time with it, and I'm about to move back to my Mom's where I'd have a garage to do it in. (but I haven't told her about it yet...)
I could use the $500 i'd save and spend it on exhaust which i'll probably need, but I'm still not sure I won't just let the shop do it.

I called Toyota and he told me it can't be done from the numbers on the block, the only way to be sure is to have the vin number from the car the motor originally came from.
I wonder if there is a Toyota database that has a record of what block number went into which VIN, but I get the feeling even if there is one I won't be able to find anybody with access to it.

The used part/salvage yard that I'm going to is a pretty big place that has pretty good info and they show it being compatible with several from later years, assuming it is a 98 Camry but I'm still guessing at that. The numbers on the block just say 5s xxxxxx there's not much difference in any of the others I've seen.
But the used part site has a note that says there are slight differences in the way the EGR is.

If anybody has any insight to the compatibility or how to identify please chime in.

The worst part is I am still assuming the motor I have is a 98+ Camry because of the way they shaved a chunk off the transmission to make the oil pan fit.
It still really don't know what it is. And if I'm gonna have the time off I may as well have this head I've got worked on. f

All of the interchange info I've seen shows a different 5s for '96 and up on both the Celica and Camry would have a G 5th digit VIN, and the 94-95 has an S 4th digit.
But that showed the same for Camry and Celica, other information I've seen said they kept the one style in the Celica up through 99 and then had a slightly different 5s in the Camry
From 98 on. But from what other people have been saying the actual head gasket and water passages are the same so the head gasket is the same as long as you get an MLS gasket.
But I wonder if the complete head kit would have all the right seals, the notes on the interchange info from the salvage yard said there are some differences in the EGR on some.
