Did you have an issue with them pumping up at high revs or something? If not, why did you do this? Generally the purpose for doing this is to get lighter lifters, and those steel inserts of yours look to be somewhat heavier than the oil that they replace. Also, if you didn't block off the oil passage, it will fill up and be even heavier than stock at which point you are behind the 8 ball. I'm not sure I understand why you have done this at all really.
Secondly, if you were to make it interference and snap the belt with HLAs in there, you would still bend the valves anyway. HLAs are as hard as steel (liquid is almost totally incompressible) and won't cushion the blow at all.

Firstly, the engine is non-interference in stock form, so you won't bend the valves even if you snap it even with solid ones.
