I'm rebuilding my 1FZ-FE and I just got the block back from the machine shop. I specifically asked them to not clean the block with a caustic mix as to not damage the oil pump bushing, and they told me they used detergent. After picking up the block, I noticed the bushing is a little discolored but doesn't seem to be corroded, damaged, or weakened in any way. The bushing is smooth, there is no scratching/pitting/etc, and looks good. What are your opinions? I thought this was a brass bushing...it seems to be aluminum or steel?
Additionally, does anyone know where I can find these freeze/frost/expansion plugs? The machine shop took them out. Is the part number 11431B / 96411-65000?
And my last question has to do with head bolts or studs. I am heavily contemplating re-using my stock head bolts after reading every thread I can find on this forum. They meet OE spec according to the FSM and can be reused, but I've also considered going ARP Supra/Opel studs as they're cheaper than a brand new set of OEM bolts. I'm using a factory new-style OEM Toyota HG, and I'm curious from those who have used ARP studs... 1.) did you retorque and 2.) what torque values did you use - ARP's or Toyota's?
So to summarize:

So to summarize:
- Is this bushing still good, would you reuse it?
- Is that the right part number for those small freeze plugs? Probably 1/2" wide in size, dime shape. Does anyone sell a complete set for all plugs?
- Would you reuse your factory head bolts? If you used ARP, did you retorque after X miles, and whose torque specs did you follow?
