what year is the block?? if you have to put the knock sensors on the side of the block and the cam sensor on the front cover then you have an "ly6" the updated verson of the lq4 starting half way through 2007.... it should have 2 valve reliefs on opposite sides of the piston.... if none of that applies except for the having 2 releifs on opposite sides of the piston then someone may have put updated floating rods and postons into an older lq4....05+ rods are beefier and have floating pins

Seems the later LQ4's have these pistons and they look identical to the LY6 pistons. A friend of mine had an LQ4 from an 07 van and it had the same pistons with reliefs in them. Quick internet search netted me that guys have seen it in 2005+ Lq4's.......
