I'm going to put together a 383 for my camaro, I was wanting some oppinions on heads. I was looking at getting a set iron eagles, but I found that a new set of Brodix's IK200 is the same price or cheaper and they have great flow characteristics. What would be a better choice. My engine is will spin 7000rpm. On a solid magnum cam, and 11.1 comp. and I plan on running some nos.
