You don't hear a lot about them as they kind of get lost in the overflowing head world right now. A lot of people are buying the cheap chineeaey aluminum heads thinking silver is better. The chineeasy copycat a good set of heads made in the U.S. but even copycat the name to unsuspecting buyers. I would take these over any chineeasy head and may be one of the best iron heads out there. With that type of flow number and most any cam on a 400/406 sbc would be awesome. Type in 406 Chevy Impersonator on Google .Should find a Chevy High Performance build. Sub this pair of heads for the original vortecs or in their second build the AFR's (like to have a pair but cannot afford) and think what you would have. Buy a few sets of tires . You will need them.

Nicely said and done. now that the intake problem isnt a issue like everyone says it is... we can now say we have 500 hp heads but.. retain every foot pound of torque on the lower end on a 406 because these are vortecs and designed for torque. looking forward to 500 ft + and im not going over 6400 rpms
