What integra and what civic?

Do they have the same engine? Example is B series integra and a B series civic which is not in the 7th gen civic.

7th gen civic would be EP3 which did share an engine from an RSX (Integra replacement).

it's a 01 civic lx so would that share any acura parts and i don't think it has a b series in it, and also would a crack in the header cause it to overheat?

If your in canada the 01 civic will share the Acura EL engine. If your in the US then it does not share engines with an Acura.

You have a D17A1 engine. Cracked exhaust manifold is a common problem with this grn civic.

Google D17 cracked exhaust manifold.
