Recently blew a head gasket and decided to port the heads & intake while they were off. Got them back from the shop topday & they look AWESOME...can't wait to drive her again...been 4 weeks now (did it all myself except fot he deck milling & valve grind). Anyway, I'm needing torque specs for the Heads and Intake manifold so I can get everything buttoned back up. Thanks for the help...
