I am running the Woods .650 cam, and it is way loud due to the quick ramps. I am not running roller rockers and see no issues, but I dont regularly buzz the motor beyond 4000rpm.

There is no need to run rollers on the 575.

 

No need Brad...

They are louder, more stuff to break, they don't roll after about 3k anyway.

The only benefit is to the margin ($$$) of the guy pushing boxes.

I took them outa my motor and went back to stock @ Dougs recommendation.

I have a set of TP's I'll sell for $200.... I like box margin too! Any takers?

 

I have em, don't find them that loud. 585 cams

 

Thanks y'all. Looks like I don't need them and won't get them. Can't wait to get the rest of these parts collected[8D]
