Are there different versions of the 317 head? Re: head bolt lengths Title kind of states it.
I was wondering if there were different versions of the 317 head used on the LQ4 that would use different style head bolts.
Longer info:
I bought a low mileage 2004 LQ4 for an engine swap many years ago. I visually verified the donor truck and have the vin handy which also matched the claimed 2004. I also have torn into the engine and found the "unequal" head bolt setup and NOT the expected equal head bolt setup. Did I get a rollover LQ4 from 2003?
