My question here would be, why would you want to run that big a head on the street in the first place?
On the street torque is king, a 170 or 190 port volume w/ some 202's would work so much better, unless you plan on running a pretty steep gear( 411 or higher) and high stall (min 3500) and huge bumpstick those heads will be worthless on the street, those heads are for high reving horspower for the likes of the drag strip. maybe your building a saturdaynight illegal street racer< i duuno, driving that beast to the night's racing spot would be brutal, Id trailer it close then cruise up and waylay the comp.
