Jeff you went with the Morel Ultra Pro .904 lifters which are pressure fed lifters, Which was a great choice !!!
To date I have never seen any one that had any issues with .904 lifters.
I am still on the fence on bushing lifters !! Over the last few years I have had calls and emails about problems with those lifters.
To the OP if you go to a bigger lifter its a good way of getting the lifter bores corrected to blue print.
Here is a good article on lifter bore placement on page 52
