its not the gasket, its teh headers. specially "megan" which is a pretty cheap brand

any cheap brand headers you buy, u'r gonna have an air leak somewhere, but its xtremely rare that u get lucky.

i went through two different sets of cheap headers, they always had a leak in them. even when i used the stocks gasket.

now i'm just running oem manifold, not going to spend too much money on DCs. i'll just put that money towards a big motor upgrade.
