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

[VavAlephVav]

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.

there should be a VIN tag on the block unless the junkyard took it off. the tag is riveted to the back of the block
