440 source 1.6 roller rockers, opinions?, experience?

440 Source rockers are very NOISY.
That being said,I would buy the right part for your build.
I have a set on a 512 ci. engine.
It has a Comp .545 hyd lift cam.
Stock Eldelbrock heads.
Anything more than this cam I don't know if I would use them.
That being said they did get my 67 4200 lb charger to 11.80's.





These are the 1.5 rockers.
