how does your mopar size up to brandx...????

Your top pic is a small chamber closed chamber 305 or less sbc head. They have open chambered heads just like the lower pic. Dont play this details bs. Its still the same ******* design basiclly. Not much different but slights from one to the other. All to promote swirl and better efficiency in the combustion chambers. Neither are canted and the valves are inline to another. Tomato tamatoe
