Default intake ?

Dose the intake manifold bolts have washers for a 66 corvette? Do they have washers? Thank you

I have never found any lock washers or flat washers on a factory assembled small block engine from the 60s era. Not saying they are not needed to prevent gouging of the aluminum intakes, but I don't think GM installed them at the factory. Bean Counter Savings you know.

No problem, if you corrected all of my posts, you would be a very busy man. It happens.

Use thread sealant, especially the ones under the carburetor both sides...

I know the factory didnt use washers but personally I think it is a good idea to use them for the aluminum intakes.

^ Agree. The Corvette vendors make small thin stainless washers for this purpose, that are somewhat unobtrusive. You may still get dinged on judging for using them, if that's a concern.

I have those small, thin, stainless washers on my 340 horse 63 aluminum intake. They fit perfect and almost invisible. 👍
