what is the difference between E7TE heads and what i have. i have a 1984 carb. mustang. i think i am going to get a pair of these and take my edlebrock intake and they the heads rebuilt and have them ported and polished to match the intake so i can get better flow. but yes what is the difference?[]

 

the e7's are better heads than what you have,i "think"you have the old
e6 heads.
