air bleed with plenum coolant bypass

[brentoleary]

I am planning to put on some SAMCO hoses and bypass my plenum coolant as outlined in the April 2007 Heart of the Beast article. I saw a few pictures where it appears others have bypassed the plenum coolant without air bleed hoses as shown in the write up. I like the cleaner look of no top end plumbing, but I am far more concerned about functionality than looks.

Any thoughts on the bleed hoses?

Any advice in general for the job. This is my first attempt at doing anything to the Z, so I am excited and nervous at the same time. I have a 1995 factory service manual from a previous vette, is it worth ordering the 1991 specific manual and the LT5 supplement before I start or is the 1995 manual close enough for this job?
