1971 Demon 340 T/A build help

no,..not for extra porting, T/A heads dont have push rod pinch from factory cause push rod hole is moved over, hence the off set T/A rockers, more to them than just big valve X heads!!! very big difference in availability and price!! ant trying to bust your balls bout this, just trying to help you understand the difference!
No I understand, its not a t/a challenger nor is the block a T/A stamped 340 or heads unless you bought the Challenger, im just trying to build as close as possible tribute to that or exceeding, my block is cammed and dyno’d at 385 horses which surpasses t/a numbers, and sway bars are 1” hellwigs chromemoly which far exceed the factory t/a style sway bars at .95” as well, so restomodding on improved items that are available while also retaining some of the classic elements of the package is the goal overall
