Heads for 440

Car Nut said
Summit Racing has a sale going on, you can save $120 off each Trick Flow head.

Code EARLYP

How do you use that to get 120.00 off EACH head? also, i noticed summit has 1 more set of e-street heads..i could use the coupon for them also,,wonder if they would do as good as the 440 source stealths?
