Lets talk small block stroker cranks

I'm not a guru but reading about BBC's with the 4.25" crank, it is recommended to use rectangular port heads to make the power. The ovals will give you more low end torque at the expense of top end power. A large inch short block could be built now, use you r current heads. If acceptable, leave as is or replace with a higher flow head later.Only my opinion,FYIW.
