Auto decomp cam in an '02 WR250

All the information I can find says to put an exhaust cam from an '03 into the '02 and you get auto decompression. I did this back in '03 and it worked a treat. I have since sold that one and moved on to an '07 450. I recently purchased a near mint '02 and want to auto decompression this one too.

My question is what cam can I use for this swap? Does it need to be an OEM '03 or can another year cam be used? Or a Hotcams?

All the info I can find is really old so perhaps when people started doing this swap "03 was the first opportunity.

Thanks in advance for any information

Also, I am not looking to necessarily increase performance. My main goal is auto decomp.

Either Hot Cams or 03 and newer. Doesn't have to be an 03

Swede is correct.
