From what I remember, a push rod checker for a stock 440 won't work (too short). The Trick Flow heads are about an inch taller, OP will need a longer one.Its better to check what You need vs random guesses. Buy a push rod length checker and check them. CHECK IT, CHECK IT, CHECK IT then buy what you need. There are videos on youtube if you need help checking the pushrod length. Pretty sure stock length is 9.295 in.
