New to w-2... Horsepower / torque ??? Bye bye Hemi. Hello w2-340

I would go ,solid flat tappet.. Just ,my opine.
Solids : flat crunch reliable, give wayyyy quicker response.. to those heads ..
J.M.H.O....( more torque ,got flow numbers , ...or pictures?)....

I bet the guy that got the 528 hemi is still laughing ! If it was in good running condition.
