D0OE-R Cobra Jet and Super Cobra Jet head castings.
Combustion chamber volume comes in slightly smaller at 71 to 75 cc's  11 to 1+ compression ratio with 429 flat tops, or with the dished 460 pistons.
About 1/2 point lower on '72 and up blocks.
Cobra Jet engines built before 11-'69  had adjustable valve train. They were  non adjustable after that date.
Adj.castings came with pushrod guide plates,sled fulcrums and stamped steel 1.73 to 1 rocker arms
Adjustable valvetrain used non shouldered rocker studs. Non adjustable valvetrain used positive stop shouldered stud with 3/8" fine pitch threads on top..
All Super Cobre-Jet engines used a solid lifter camshaft.and adjustable valve train.
Valve sizes are 2.24" intake and 1.72" exhaust.
Intake ports are larger at 2.51" x 2.11" ovals
Exhaust ports are also larger at2.25" x 1.30" rectangular oval port shape
Although the exhaust ports are larger they share similar architecture with the passenger car castings. Removal of the thermact-air boss along with blending of some of the weird casting bumps will help flow measureably.
All of the 385 series castings suffer from a very poor intake/exhaust flow ratio.
This due to the fact that shock towers in the intermediate line up neccesitated tucking the exhaust manifolds as close as possible to the engine for clearances' sake
