lq4 6.0 swap into '85 Crew Cab Shorrbed

[Ranger6202]

I believe they're the 2010 manifolds, but i don't know, when you search the SN's you get 6.2 for the description. The block they came on was supposedly a 5.3 out of a truck. My friend got the motor from a dealership that had the motor replaced on warranty. He gave it to me cause he was moving to Florida and not wanting to haul a mystery motor with him. I tore it down and found a cylinder sidewall blown open and a bent piston rod. The block has the 4.8 5.3 stamped on the outside, so i know those manifolds probably didn't come with it, since the 2010 camaro's are 6.2's right? I'm guessing the dealership threw them on there for some odd reason.
