it could be motor mount or valve tick...
motor mount = easy fix
valve tick = oouch

how long has it been since the last oil change...if it's been awhile, then get it changed as soon as possible. make sure your oil/idiot light aint on.

check the oil dude

or it could be a sticky valve like wraith mentioned

how much would it cost to repair that? it only happen every once in a while and most off the time it only happen when im under the hood reving it not a clunk sound its more like one loud click and the motor hesitate alittle. after that its fine.. it never did that before i had an intake in. and also the intake is custom.

depending on if you have hook ups at shop... Anywhere from $500 to $2000 and that is also depending on what they do to your head and how extensive the damage is ...
