Sometimes offset adjusters are used to move the pushrod over and make more room for intake ports when the port is widened and breaks through into the pushrods slotted hole. It's never needed for stock width ports, at least that I've ever seen. They shouldn't really be needed on your combo unless some serious porting has been done. Looking at the pictures the adjusters all look centered, but it's a little hard to tell without measuring. Are the pushrods centered in their respective holes? As long as they don't rub the ports significantly, there shouldn't be an issue.
Just an observation, so don't take it wrong, but those rockers seem to have some questionable casting quality in places. Are those pits and casting flaws on the end by the adjuster in this picture?
Aluminum rockers really need to have quality castings or they are prone to breakage. The adjuster cups also seem to be of marginal depth. Not nearly as deep as all others I've seen. Both of those issues would cause me concern.
edit: I also don't like how there is
barely enough room for the adjuster screws. Even though they are showing about 1-2 threads at the bottom, which is ideal, the adjuster screw doesn't even come to the top of the jam nut. If you have to adjust the screws down at all, then they will be well below the top of the adjuster nuts. In that top picture some of the adjuster screws are half way down the jam nuts threads already. Certainly not something I would be fond of, personally.
