Rhoads lifters

i have read some older posts and it seems people were happy with them. my 360 runs very well but idles pretty rough with the hughes whiplash cam. will the rhoads smooth out the idle?
will there be a noticable improvement in low rpm performance. motor is in a 69 barracuda convert. 904, 7.25 with 2.76 gears
You can expect lower idle speeds without stalling and higher vacuum by 2-3 inçhes.
It will have great power taking off and should let you shuck all the ring gear teeth right off that 7.25
Maybe a dana 44 out of a 97 grand cherokee would be a good swap soon. 8.75 a body axles are expensive these days but an aluminum dana 44 might be cheap enough to justify fabbing up spring perches.
