Air Manifold Holes
« on: May 06, 2018, 06:36:13 PM »
If I remove the Air manifold from the exhaust, which screws can plug the holes in the cylinder head? Are the screws tapered?
I read you can plug them with brake bleeder nipples. Do you know which size?

Those holes are 7/16-20 SAE American Fine Thread.  We usually use socket set screws as those disappear nicely beneath the surface.
