Atk sbc aluminum heads?
 

Like the title implies. Anyone ever use these heads. Supposedly they are cast by the same people that do profiler sbc heads. According to someone over at atk just curious if anyone has any experience with these heads. In particular the 195cc with 70cc chambers. Thanks to any replies in advance. I'm looking for user experience, not retailer info.

While I have not personally used them I have met a handful of people who have. They are quite content with them and "beat" on them regularly, however there was one incident where it dropped a valve after 30 miles. BUT, that was after the guy changed the valve springs him self for the first time ever.

Let us know if you have any questions, they are one of the best heads on the market that are under the $1200 a set price range and 100% American made!
