Moving right along now and gaining some momentum on the car.
My intake is pretty much painted now. Took a long time to scrape off some old paint, clean in all the nooks and crannies and then tape all the sealing surfaces off. I think it turned out pretty good though:
I am now working on getting the intake installed along with some new sensors and I have a few questions I was hoping to get some help on:
1. I need some help selecting the correct intake manifold gaskets.
My heads have exhaust crossover holes:

But my intake only has an exhaust crossover on one side (the other is blocked as part of the casting):

Finally, my old gaskets have exhaust block off plates but one is missing (perhaps on the same side as the casted-in block off on the intake):
I don't really need the exhaust crossover... so is there a better way to block this off?
2. My fuel rails are all cleaned up, and I want to put new O-rings in before reassembling them.
Any idea where the get the correct ones? I'm thinking I can maybe call Accel and see what they recommend.
3. This sensor was mounted under the plenum on the top of the intake manifold. I'm assuming it has to do with measuring the intake manifold pressure, but
any idea of it's official name? I can't find it on RockAuto.
4. Lastly, I would like to order a new fuel pressure regulator.
Any idea what model this is? It doesn't have any markings on it, but it is adjustable based on the screw on top.
Thanks for all the help!
