Difference between 862 and 706 heads?
I have 706 heads on my truck and a set of 862's in the garage and was wandering which set would be better to build?

Ok, thanks guys. I was pretty sure that was the case but you never know on these things. I guess the only difference would be that the 862's were casted for 99-02 trucks and the 706's were casted for the 03-07 trucks.

(Banker099) A little off topic but I noticed your running the 3.90 gears. Are they the Yukon gears, how do you like them? I'm seriously thinking of swapping to those within a few months.

Just watch if they have a casting mark under where the rockershaft bolts on that looks like a little battery, they are known to crack! 99-02 4.8,5.3. I've had 2 sets!
