I'm running L19's, not sure on the torque specs but I will ask the shop if you really want to know.

90 ft lbs is not enough torque. I'd take the L19 to at least 105 ft lbs if you are running high boost/cylinder pressures.

We've run the Cosworth gaskets in the past, I never found any benefit to them.
