Replace main seals when doing a swap?

I'm putting a built bottom end in my integra. When I take the tranny off of my old block, do I have to replace the main seals?
Thanks

Are you talking about the main crankshaft seal? If so, it wouldnt hurt to replace them while everythings out. Itll suck if it leaks and drenches your clutch in motor oil. Happend in my old CRX when i got the ZC swapped in. Didnt think about replacing the seal, then about a month down the line the seal started leaking, got all over my clutch and made it slip like hell. Had to take the tranny out again
