Default Using IRF640N's in Balanced Zen Preamp

Think itwould still be ok? The gate capacitance increses about 5x what it is for the IRF610 in the schematic. The only reason i ask is that i have a LOT of IRF640N's laying around that I dont know what to do with...as well as some TIP142's...any ideas?

They'll work fine. Little bit different sound, that
you might prefer, but no difficulties
