    Rated 4 out of 5 by from Pro Maxx Mopar big block Pretty nice heads for price. The only negative is need some port matching which I was going to do anyway. But they have a little core shift matching the gaskets. Should be able to get them to line up ok.

    Rated 4 out of 5 by from Great looking product Heads look like a high quality product. I would have given 5 stars but I haven't started by engine yet I don't expect any problems.
