Mopar '340-X' Heads vs. Chevy 'Fuelie Heads'

Abodybomber said
I remember some of the earlier 461 castings,have bigger cc exhaust & a higher short side radius on the exhaust ports. Compared early '62-'63 castings,to later '66-'67 castings. Both unported,don't remember valve diameters... You know anything,about this 69 440 ?

Correct Mr. A-Body-Bomber

#3782461 Heads

Came both with > 1.94 / 1.50 and 2.02 / 1.60 Valves from 1964 and on.

The 1961 thru 1963 Heads, were definitely 1.94 / 1.50 {only}.

On the Exhaust Port, some of the Heads did come through with larger volume {63+ CC's}.
