My heads are stock

Heat treated roller tips to HRC60 provide superior resistance. All rocker arms come with polylocks.
These sell new for $240.00.

Also would this mean they are slef aligning or non-self aligning?? And what's the difference...will I tell a difference with stock heads?

 

Are stock LT1 studs 7/16 or 3/8 ? I guess that is what I need to know!

 

Stock LT-1 studs are 3/8".

Replacing the studs is realitively easy, but those rocker sound like the wide-body types since I don't believe you can get a narrow body with a 7/16" stud (I might be wrong), and the wide-body (or regular ones) won't fit under the valve covers without modifying the ribs in the valve covers to clear them.

PS: I didn't see where they said self-aligning, so I would assume they are not. Most aftermarket rockers are not self-aligning.And if you want to run non-self-aligning rockers, you need to get guideplates and hardened pushrods.

 

Here is a link to the ebay auction...let me know what you think!

They also have a set that are 3/8ths

Thanks! I just did the "Buy It Now" for $50!!



Just kidding.

Those are definitely the non-self-aligning type. They're also wide and you'll need cover clearancing, guide plates, and hardened pushrods for those.

Also, I don't see the little screw in locks that go in the center of the nuts.
