Often folks will shift the car somewhere just above peak hp for best ET's.

Plus what about a missed/late shift or such?

IIRC Ryan's deal is a M/T,and rev limiters can only react so fast,so I dont see any real downside to his using a solid cam in his build.

Airflow on the "box stock" Eheads or KRE-D's aint all that much,what's that,like 260 - 270'ish cfm or so.

So that's nothing to write home about,that's for sure.

Most people buying/using "box stock" aluminum heads are'nt doing so for the better flow numbers,they're usually doing that to avoid the hassles of messing with 40 yr. old iron heads and their potential issues.

And often they want the ability to run a slightly higher CR safely on pump gas.

Dump the money into ported iron heads or buy some Eheads is usually what they're pondering,and $ for $ common sense says the aluminum heads are money well spent.

Plus the aluminum heads have much better resale value as well.

Plus slowing a car down is'nt always as easy as it sounds...

It all makes perfect sense to me.

FWIW
