Small block headers: worst to best fitting. List your experience.

Thanks for all the info guys. I hear people talk headers, but not everyone get needed info for their own projects. Knowing that current Doug’s and TTi offer the easiest for driving street cars is great. If someone also has some experience with race heads, good or bad, let us know what you though of those to.

Newbomb Turk, thanks for sharing your experience, as well as the others. Hopefully we can get enough people to response with their own experiences when dealing with headers.
