exhaust intake nuts

[marfulle]

I had a thread a few days ago on this. I found some brass nuts for the intake and exhaust. They don't have the little cuts in them like the original but they are brass (someone said I need brass). All I need now is the washers. Any ideas. Can I use regular flat thin washers or do I need to find the fat ones. I am ready to install my motor and this us basically the only thing holding me up. Thanks

I believe your answer is in the original thread.

Eric, the ideal setup is the split and tapered nuts with the thick washers which have a tapered hole. My opinion, FWIW, if this was the only holdup on the project I'd use automotive (grade 5 or 8) nuts and the thickest washers I could find, also in a high grade. I would even think about doubling up on the washers. Later, when you find the correct nuts and washers, you can replace them one at a time without damaging the manifolds. The purpose of the special nuts and washers is to avoid having them loosen up over time. Also, these manifolds don't need a lot of torque to snug them up. Better to snug them up and re snug them after some driving time.
