They seem to have a decent reputation. I picked up a set for a 440 build I'm doing and think they'll do fine for my street / strip application. The valve reliefs are plenty big and the finish machining looks good.

The only thing I wasn't impressed with is that my pistons are quite a bit heavier than advertised. The spec was something like 686 + 141 for the pin and they were actually 703 + 156, IIRC. I wasn't expecting that much extra "beef" compared to the 650-ish gram Rosses my other engine uses.
