Which Street Warrior? These come in square bore or spread bore, polished or not, for 1955-1985 center bolt angle of 90 degrees, or 1986 to 1995 centerbolt angle of 72 degrees, or 1996 up Vortec bolt pattern. What ever the part number of this intake is will dictate head choice with in a group. Once that's know we can aim you at the best and most cost effective solution. There are some decent to excellent head choices that are new or rebuilt that are not Vortecs available from either the factory or the aftermarket. There are many factory heads to stay away from as well.
After today, I'll be out of touch till Tuesday.
