Sounds like a typical "frankenstein" reman engine. Two different heads for sure. With vastly different sized combustion chambers. Gotta real winner there. 84-up block, one 75-77 head, one 78-84 head, 77 casting intake.

Does your truck pull to one side under acceleration, like one side of the motor has bigger valves....

Same valves in both, but differerent chambers. The D8OE head's chambers are a full 10 cc's bigger than the D5 head. That's about a full point in the comp ratio just by a quick guess.

Dissimilar heads
I can't believe it either. Perhaps the D5OE is actually D8OE but the number is a bit smeared?
Another possibility is that the rebuilder skimmed off enough material from the D8OE head to make the combustion chamber size similar to the D5OE.
So I assume the intake and heads are off of this engine?
