223 Manifold Bolts

1958FordF100

When I got my 1958 F100( 223 ) the head was off and it only had the exhaust manifold. I recently picked up an intake manifold on Ebay. I have no manifold bolts.

I was told that they are 1 3/8 long, 3/8, and 16 threads. I went down to the local hardware store and purchased some 1 1/2 inch 3/8 bolts but they were too long so I am now trying 1 1/4 as they do not sell 1 3/8 long bolts. I also purchased grade 8.

How is the intake manifold secured. It appears to require washers to hold it to the head. Is this correct? Can anyone send me a photo of your manifold with a good view of the bolts.

The exhaust manifold has holes in the manifold itself. Are all the bolts the same length?

Does anyone have a source for manifold bolts other than the hardware store? I could not find any online?

Any help is appreciated.
