Sometimes a deal seems just too good to pass up. Take for example a set of Chevy 882 cylinder heads I picked up for a measly $50 bucks. Of course, they were grungy, had a unknown history and definitely needed a lot of machine work. But still a good deal, right?
So with the help of Dart I got the chance to test the theory. Dart provided a pair of new Iron Eagle cylinder head castings. They can be had for less than $1200 fully assembled with valves, springs, retainers, locks, guides and rocker studs. With the help of race engine building outfit Automotive Specialists,we machined the Chevy heads to get them back up to spec and tracked the costs. Once they were ready we also compared the performance of the two sets of heads on both the flow bench and on the dyno.
Given the improved casting quality and improved designs of the ports and combustion chambers, we figured the new Iron Eagles would win on power. But there was also a surprise when we added up the cost per horsepower ratio. Check it all out in the video and let us know what you think.
