Responding to the posts about the T&D rockers. The two knocks that I hear about the T&D set up is that the heads have to be modified to use them and you need to convert to pushrod oiling. They may be overkill for a street engine but if you're willing to go thru the effort you'll end up with the most durable FE rocker system available.

We use them on our FE race engines and they have been virtually bullet proof. My engine regularly see's 9500 rpm with over 1000 lb. valve spring open pressure and the lash stays rock solid run after run. They've even seen 10,400 rpm once (broken transmission) and lived to tell about it. No other FE setup that I've seen could survive that.

I have a set of customers Dove HR heads at the shop now that we are converting to T&D. We make a custom lower mount bar for the HR heads. He ran Dove rockers previously and ripped the top of one of the intake ports right off the head. This isn't a hit against the Dove rockers, they work great in most applications, but they do have their limitations and that's where the T&D's take over.
