get the heads, clean them, port them, take .010 off and put 1.7 rockers on them. leave the stock cam and youll be happy. work mostly on the exhaust ports, as the intake side isnt too bad. gt40 heads are stock ported heads from ford so save the money. im sure everyone will say this is no good but ive been doing it for 12 years and never heard any complaints. doing what i said and a few intake upgrades will get you in the low 12s.
