[Roadsters] manifold bolts

[Tim]

I poked around 311s and didn't really find what I was looking for--no surprise there as I am "search handicapped". 

I want to have a new set of manifold bolts on hand for when I attempt to install new carbs next month. 

Where can I get them? Send me some part numbers and a source please. I think I would prefer stainless if available. 

This is for a 70 1600 that has been desmogged. 

Thanks

Tim
