i have a 1996 mustang GT.. wondering what would be a good head swap. i have heard that 99 GT heads really wake up the 96 motor. i have a 1996 4.6L truck motor. would these heads be a better design than the older 96.also the injectors in the 99 truck motor would they be bigger than stock 96 injectors. i realize i would need a comp chip. thanxs for the help
