These heads are the highly sought after "243 Z06 Castings". The combustion chambers is 64.45cc and raised D-port exhaust ports are just a few of it's features. The heads flow stock at 250cfm on the intake ports and 200 cfm on the exhaust ports. The intake is 210cc and the "D" shaped exhaust ports are 75cc. The LS6 chamber yields a 10.5:1 compression ratio with standard pistons. The heads feature a 2.00 inch Intake Valve and a 1.55 inch Exhaust Valve. These heads feature better springs than other GENIII type heads. The Valve Springs themselves are capable of handling lift up to .550 inches.
These heads have been known to add as much as 11-19 kW with no other mods. If you add the right camshaft, these heads and cam can add as much as 37-56kW .
The retail price for these heads is $2680. I am selling these for only $1490
