Chevrolet Cylinder Head Dyno Test

From http://www.horsepowermonster.com
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 http://www.horsepowermonster.com/2011... . Thanks!
