Calling all gen 3 hemi gurus

i bought the g3 lifters and not stock rollers. just to make sure i didnt break a 1200 cam and 800 dollar lifters or worse.
piece o mind vs pieces of engine.

i think it also has to do with machining and pushrod length to non adjustable rockers being a big factor. they have a window of acceptable tolerance which is or can be say off from on end of the block to the other.
