i'm running ported stock e7's an crane 1.7 r/r's.....got offered a good deal on a set of twisted wedge heads an was wondering what all is req to use them besides the stud rockers? thanks
Buy them, they are probably worth a good 40-50 hp over what you have now.
But, have a machine shop go over them, people run PV clearance alot closer than they should.
