This may be a dumb question but are the driver side and passenger side heads the same? One has the number 4 on it and the other has the number 6 on it, they look identical I just want to know if they are. Any info on this will be appreciated. Thanks.
yes, they do both have that number on them. next question, I just got them from the machine shop, should i put the heads back on the same side they came from or does it matter? Also, what are the torque specs? Thanks again for the help.
