A little less friction never hurts (less guide wear at the least).

I installed a set on my 355 I like them, but I'm not sure how much gain you will notice, but like bstmech stated less friction the better. They are fairly inexspensive.

Should make your valve guides last longer due to less side pressure. I consider roller tip rockers as a good value for valve train modifications.

Actually, the benefit of the roller tip rockers over the stock rockers is that the ratio will be more consistent and closer to 1.5:1

The stock rockers from the factory can be anywhere from 1.37 to 1.45 so you're not getting consistent full valve lift.

Roller tips can't hurt if you need that last bit of performance, slightly lower oil temperatures at the valves and you have the extra money

Good Point!

Also, there will be less deflection as they are stamped from thicker metal. Just the lesser side load on the valve stem is worth the price. Less friction...less heat...frees up some power...it all adds up.

I can see where you would not want to go the the expense of full roller rockers, but roller tips just make good sense.
