Exhaust tube diameter
Posted by: zarfnober ()

Anybody have the outside diameter of the small valve head exhaust tubes? I’m planning on building a mandrel bent crossover for my turbo, and want to use the 140 logs, but want to prevent any possible exhaust leaks at the tube/manifold. So looking at the size that clarks shows as the ID on the 140 packings, I was thinking that 1-1/4” OD exhaust tube could be cut to fit, and tacked on. Thoughts?

Turbo heads use same exhast tubes and logs as the 80, 95, 102 & 110 engines.

I want to say small valve heads have @1 3/16" OD on the exhaust tubes.
