10 degree GM wedge heads

What's the part number to the 10 degree small block head, and where do you get them?

25500141 – Buick or Chevy aluminum, 10 degree race head, 42cc chambers, symmetrical ports, 235cc intake ports, 2.1/1.625 valves

Thanks, but not the Dart Buick. I have 3 sets of those. Some got ahold of them early when they first came out, and one well know comp SS racer told us they're hard to get but well worth it. He said they were .15 to .2 better then the 615 15 degree head.

Thanks. It may be bogus, I've checked on GM performance and none are listed, but I've seen one set on a top car, and I see CFE builds an intake for them, but they must be a figment of my imagination. I will check though.

I have always been under the impression that CFE and SLAWKO are the only two that have really rolled the 615 castings over to 10*. I'm guessing some welding has taken place to allow that to happen, but I know it was never a GM casting that started at 10*.
