Cheap Small Block Chevy Aluminum Heads Made GREAT?!

How do you make a pair of cheap aluminum small block chevy cylinder heads great? You send them off to Eric Weingartner for some expert porting work to increase their flow! With years of experience improving everything from budget aluminum heads to expensive race designed heads, if anyone can make these budget bit better it's Eric! These are the exact same heads that came off our budget small block chevy build we did using a 406 small block chevy, and a full top end kit from the folks at Jegs. How much flow did we gain from all his hard work? Let's bolt them down to the Superflow head flow dyno to find out! As always huge thank you to Bob McVay of Street Racing Channel and The Old Man's Garage fame for his work and willingness to work with me to get these projects completed!
