These heads are 862 castings (5.3L). They were ported by Total Engine Airflow (www.totalengineairflow.com). They include Ferrea Valves,2.055 intake, 1.550 exhaust with swirl finish. They are a beautiful set of heads. Full CNC ported and NOT milled. Heads are also brand new castings from GM. No springs. I was going to use these on my next project.

FLOW numbers:

LIFT INTAKE EXHAUST

200 133 99

300 202 139

400 259 190

500 293 206

600 296 215

700 298 221

Combustion Chamber Volume is a little larger than: 61.15cc because the bowls of the head were CNC'd which should give around a 10.9-11:1 CR.

Just want to get back what I paid. $850.00 plus shipping.
