ok so heres the deal... tomorrow i may be trading my built gsr head for a gsr block and b16 head, and i was wondering what i should look for in the block. the pistons and rods are out of it, and the head is off so it is partially dissasembled.... im basicly looking for tips on what to look for, to make sure that everything is legit... i was also wondering if the head( came from an 89 sir will flow as good as any other b16 heads, it has a 2000 si intake mani and throttle body and also a port and polish...) let me know... TIA

 

anyone???
