building motor help needed
So i finally put a rod through the block looking for about 500 hp. So I am getting another rotating assembly im thinking for parts cp pistons, manley rods and spool import billet oil pump gear then swapping my head over. http://www.rawbrokerage.com/cp-pistons-manley-rods-combo-r33-rb25det/
Im not to sure what head gasket or thickness I need and if i should run race main bearings and end bearings or if I should just go oem.
Can you provide insight on what other parts i will need or you recommend as this is my first build.
