I have a set. They were supposed to be off a crate engine with just a few dyno runs. It didn't make any power on the dyno. They changed heads. I bought them for what seemed like a good price at the time. They sat around for years before I sent them to Dwayne. Dwayne changed 5 seats and did a lot of other work...
