Alright so I've got a freshly rebuilt streetported 13b short block, and I'm wondering what stuff needs to be replaced usually when doing an R&R and what stuff is a good idea to have replaced. Talking about stuff like oil injector lines, exhaust gaskets etc etc. Thanks in advance

 

plastic things. all gaskets and grommets. all hoses and o rings.

that pretty much sums it up.

 

All belts, all hoses, all filters, all fluids. Probably want to replace the engine mounts as well. Do the pilot bearing, throwout bearing and clutch because it's easy to access and you might want to consider replacing the front transmission seal as well. Plugs, wires, all gaskets, etc.
