#138149, "RE: New head bolts and 2.4L head bolts" In response to In response to 7
Yes the heads of 2.0 and 2.4s are essentially the same when bolting up, but the issue is that the 2.4 block is different, which is what matters since that is where the bolts thread into. So buying 2.4L head bolts will never work in a 2.0 block regardless of year.
