Would you believe you paid less than I did?
I got GT-40 X305 heads for my wife's Mustang. They take pedastal, bolt on roller rockers. They cost me $500 from Summit Racing.
They probably don't have as much of a reputation among street enthusiast as Crane or other big names, but that is due to marketing I believe. Harland Sharp is THE guy that designed the roller rocker in the 1960's. Now there are other members of his family that have the business and I toured the plant (30 minutes from me) when my son was working there. They constantly test their rockers against the competition. I saw the bodies of both laying on the floor and in a bucket at the station where they do their testing. They use 2024 aluminium that not all manufacturers use. It is a higher grade and stronger material than 6061 which is quite popular. They will also custom design rockers for a specific application, street, race, or whatever. After touring the plant and talking with the people that run it I will only buy their rockers.
One thing the company President showed me were the "knock-offs" of their designs. Some by Chinese companies, some by names such as Crane. The similarities, or should we say exact replicating, is obvious. If people want to copy your product you must be doing something right.
Ever been to their website?

Check it out, it's an interesting read. After I get a better picture of the wife's car I will be sending that to them for their "Customer's cars" section.
