While valve size matters, in the HEMI head a smaller valve can out flow a bigger one since the valve has (near?) zero shrouding and opens on a better angle into the center of the head.
HEMI head, superior flow, superior design, superior power.
I had two hemi`s, raced one for 14 yrs. The canted head rat head will take a bigger valve, cause they don`t hit each other w/ huge cam designs (lift and duration), the hemi can only go so far in that respect , they will collide ! That`s why chysler copied the rat head in the end yrs of prostock.
A rat head design can outflow a hemi when taking them to the limit. Sounds like u don`t know sh-- about hemi`s to me !-----Talking 426 style heads.
