I dub thee Frankenmotor

Oil Pump issue behind me, connected, bled and so on.  Torqued all the motor mounts.  Started to connect some of the electrical, and, well, turns out the efi cylinder head I bought off of eBay appears to be from a 2001? EFI.  There is a temp switch in the head instead of the temp sensor, why not?  I have so many different parts in to this I do not know what is what any more.  All I know is the head looks identical, so I am swapping sensor/switches and calling it good.  I had asked around on some sled forums, most said it should work, a few said to check the "squish".  Ugh.  I will check the compression before I start it, and if it is within tolerances I am going with it!
