22RE Head Only

[Fonger]

I've got a 22RE head off of an '89 Toyota 4Runner. I completely rebuilt this head. I had it machined (decked), checked for cracks (it passed, no cracks), new valve seals installed, new Toyota rocker arms and valve adjuster screws (again these are Toyota parts, not aftermarket from Napa or something). I also installed the EngnBldr RV Crawler camshaft. I got this thing all put back together and the engine ran long enough for me to break in the new camshaft (about 45 mins) and then it spun a main bearing and trashed the bottom end. The head is still in brand new condition. I'm looking to get $600 for it.
