regarding redoing heads ! or replacing engine!
Hello all ! I was wondering ! I have a 2004 f150 4.6 i sucked a valve it has 120,000 miles is it worth redoing the heads ? or should i just look for a good used engine ? and if just redoing heads is ok !! do they have to be off of a 2004 or newer? any info appreciated ! thanks !!

define " sucked a valve"
The valve dropped and made contact with the piston?
If so engine is junk IMHO
Low compression due to normal wear? what are the compression numbers in the rest of the holes? Are they close to factory spec and close to each other or are they low across the board or low from cylinder to cylinder?
Have you done a wet/dry compression test? Leak down test?
