If Brodix made the exact same heads to bolt onto a big block Chrysler block people would be afraid to run them because “they would lose torque.”

In fact they would come on here and probably get advised not to use them too.

B/RB std port heads were designed in 1956 and 1957 for 350 and 361 cubic inch engines, and designed to make good part throttle torque and response for use in station wagons and big cars. Chrysler engineers designed a port for performance use at 400+ cubic inches. Its the Max Wedge port, and again, most people seem to be afraid its “too big.”

Theres also the 426 Hemi port, thats a pretty good one I’ve heard.

There is a pretty big difference between most of the engines designed in the mid/late 50s, like the standard B/RB, Buick Olds Pontiac, Ford FE, etc and those designed in the 60s. Hemi in 64, Big Block Chevy in 63/64, Ford 335 and 385, etc. The later stuff all has much better heads and stronger blocks.
