I have used hydraulic roller lifters with Boss9 heads and the straight tie-bars worked but, the pushrodss were a lot shorter and seated at the top of the lifters.

With the pushrods seating inside the lifter and 5/8" longer pushrods it is a different story.
ISKY used to sell "high button" solid roller lifters, I don't know if they still do.

any chance the straight tie bar lifters would work with an offset seat and a long taper on the pushrod?

The reason for the need of the z bar is because of the laid down ehx push rod. I have not seen any straight links that will not cause a problem/interference of push rod thru the lift of the cam

rich,i think the intake pushrod requires the z bar lifters to clear.exhaust just has a lot of angle,but with liters to the inside of the block the intake pushrods interfere with top of the straight link

Pushrod contact with the rivets holding the tie bar is usually the issue with a straight tie bar; given the pushrod angle.
