67 dart gts 383 cylinder heads??

JJ USE,

On the 1967 Dodge Dart GTS 383 and 1967 Plymouth Barracuda 383 'Formula S'.

The Valves were {2.08" Intake} and {1.60" Exhaust}.

'No' 1967 383 ever came thru with the #906 Cylinder Heads, only #2780915-1 'Closed Chamber design'
with 1.60" Exhaust Valves.

I've had several sets of Cylinder Heads off of the 1967 383's, and never saw a set
other than with 2.08" Intake and 1.60" Exhaust with the Single-Coil Valve Springs.

Again, the 1967 Cylinder Heads did have a Closed-Chamber design.
