308 or RHS on a 408

OK cool, thanks. Just wondering for the port velocity thing. Kind of get a feel/idea/forcast it all thing in my head. The new head is indeed a nice looking part with good reports about it. When Brian did the Mag (M-Muscle) and dyno'd it, I thought I'd see a true 500 like writin on the cover. (LIARS, Shakes fist @ mag!)

I don't remember all the specs, but I was thinking the ports small for some reason.

Non the less...... The real bottom line is how well the 308's will do and there cost vs. the Indy heads as prep'd by Brian for the job at hand, not a full on HP build with 3.23's. Though that D66 and cube size ought to be real cool down low and mid range and scream up top with those gears.
