When I started putting together the engine for my 27 I considered the World heads, as well as having the early heads I owned reworked. It became apparent that by the time they were done I would be within several hundred dollars of the cost of a set of Edelbrock Performer RPM heads, so that was the way I went. I could not be happier with the Edelbrocks, they seem to really make some good HP, and look great sitting on there. I get a lot of comments on them from onlookers.

I think the World head are ok, but there are just better ones out there for not much more money.
