fast help needed
OK my son & one of his buddies got in on a engine swap of a 92' f1504x4.
now converting a 86' to a 92' 351/5.8. They have been working after hours, with it being SOooo hot, progress has been slow. now the owner wants his truck ASAP
basically they pulled a tired 5.8 out and swapped in a better (possibly), engine from a 86'. They swapped the intake from the 92' engine but used the heads from the 86' to put it in the 92' f150.
the question is... what is this exhaust port out the front of the heads (both banks) & what size are those threads???...(guessing 5/8-11 or are they metric?), so they can plug them.
the 92' heads have some sort of insert threaded in them....kinda doubt that they can be removed, gonna suspect they were lock-tighted in.?? IDK
Have they short stepped their way to a bunch of headaches by not keeping the 92' heads?
appreciate the help
