on your last picture there is a plug with a red ring on the top rear of your intake, you push the red ring in and pull out on the plug [ you may have to push the ring and plug in together and then hold the ring and pull out on the plug] and it will come out . you can use that for your vacuume for your trans and brake booster. I forget the name of the valve on the front of the intake, it has something to do with purging air, you should not need it, I have did away with them on a couple of engines, you can pull it out and block it with a freeze plug or leave it and put a vacuume plug on it. to get the plastic line off of it push the clip that is holding it on to one side and it will come off, very simple once you figure both of these out hope this helps
