bump header size for node

Previously we were getting either a generic 400 error every once in awhile, or on my end, the more specific 431 error.

Node before had a default header size allowance of 80kb, but changed it to 8kb (nodejs/node#24731). This was causing issues for our app, and forcing us to clear cache regularly. For our purposes now, I've bumped that limit up to 40kb.
