I can tell from the 706 casting on the one set that it is a 4.8/5.3L head. I think the 862 is the earlier LS1 head.

They are both 4.8/5.3 heads.

I wasn't really sure with the 862, I think I confused them with the 853's.

862's are what are on a stock '02 5.3

So what are a set of ported truck heads worth?

I found out they are 237cc heads and flow just over 300
