block off plates?
 

i have a 87 tII. i have the egr block off plate. is it absolutely necessary to block off the remainding plates? there is two next to the egr and one close to the firewall. i forgot the names of them. i know one is for the supply coolant for the turbo but i dont have the bac and was thinkin of just blocking off the coolant lines from the top of the motor. i need to get this running asap and am very close to the end. any help would be appreciated

ps. all emissions is removed

Here are some pics. The only one not pictured is the sub zero start plate which is located on the inside of the LIM

This last one is the air supply valve which bypasses air into the dynamic chamber, and is mainly there for power steering and hot start applications.

here is a larger photo of the BAC, ACV, SAP, and the Coolant to turbo pipe which is removed when you run an aftermarket turbo that does not require coolant.
