Hydraulic Roller Lifters w/LA Block?

I just called Hughes to inquire about their lifters. Spoke with Dave who was familiar with the issue and said their lifters usually do the trick and are really just Morels so the ones I already have *should* work unless the size is somehow different. Their product page HERE specifically acknowledges this issue as well.

He also recommended against grinding the cam and advised that I get the bores sleeved at a good machine shop that knows Mopar if I must do something. However before doing that he recommended that I measure the gap height on each problem lifter and report back to him so he can check to see if he has anything that will work. If I actually end up needing to get my blocked sleeved it'll be the first instance in like 5 years he's heard of it. :wack:
