Brodix sbf 15 degree head hunter heads

Does anyone now anything about these heads. Im building a big sbf n/a engine. I know the basic literature on them and they sound like they would be a good piece on my engine. There one of the biggest cc heads that i know of and they flow 413 at 800. This is my last big part to buy before i start buying all the littler parts i need. Thanksin advance.

Don't know anything about them but they look nasty!

Kuntz has a program for them. Maybe check over there. Not sure since he has passed what all they are still doing.

Thanks Brian. I willcheck it out. My engine builder has to be going crazy over all the changes I've been making on my build.
