I have the Gold Race rocker kit and it did come with 7.250 length pushrods. After asking Crane, summit and these fine people on LS-1 tech you do need different pushrods and they are not just torqued to 22 pounds.
If your wanting to upgrade rockers the Crane kit is top of the line. If they were out when I bought my YT's in 03 I would have bought them. They are expensive but just the fact of having an adjustable valvetrain is worth it. You can adjust for perfect valvetrain geometry.

Crane Roller Rockers Durability... Have been told that the Crane rockers have a life of 30,000 miles on a street engine & should then be replaced. True or false? Thanks, Gar

I think from a general observation these are very well designed rockers, which if you look at the shape you can see why the material is put where it is. The HS rockers are basically flat and the material is not put in areas that can help strengthen the rocker. Crane seems to have added material to strengthen the rocker that will be in compression rather than tension, which is key to a long life.

I'm n00b.
Crane makes two rockers for the LS1, the stud mounted which I have and their newer shaft mounted. The shaft mounted required some head machining that also requires the heads to be off the car. Had they been available six months earlier, I would have went with them but they released them right in the middle of my head installation 
Oh well, if the heads come off again for some reason I will re-visit the Crane shaft rockers.
I got one of the first sets of Dart heads when they came out and the Cranes wouldn't quite fit (Dart has since corrected this minor issue). So I fully disassembled the heads and used some tools to fix the issue. When I set up the heads, I tried the stock rockers and the Cranes on the workbench with checking springs to assess the wipe pattern. The stock rocker wipe pattern was not consistent and was very very wide. With the Cranes, I could get a narrow wipe pattern (for a single direction wipe as the LS1 rockers are) and had full control over the setup which I liked. Here are my Crane 1.7 fully adjustable stud mounted rockers on the Dart heads after I installed them.

I was considering the shaft mount rockers when I did mine a few months ago and talked to Roger Vinci about it. Roger told me that the shaft mount rockers were overkill for a street car. I do about 3-4 HPDE's a year also and he still said that the stud mount rockers would be the best fit. Retail price comparison, the shaft mount rockers without the machine work are double the cost of the stud mount.
Either way you choose to go, either of the Crane rockers are great products.
