Chevrolet Cylinder Head Dyno Test
From Looking for an answer to the age-old question (at least when it comes to engine builders), is it better to refurbish an cheap old set of cylinder heads or buy new? So we took a pair of $50 Chevy swap meet heads and put them up against a set of new Iron Eagles from Dart. What we found out might surprise you. For more information, including Dyno results and flow bench tests on both heads, check out ron-eagle-vs-stock/ . Thanks! We're constantly uploading great new videos.
