I have a 1995 Mustang cobra.The 5.0 has been replaced with a 351W.It has the Gt 40 heads on it that came on the cobra. They are in need of a rebuild,valves ,guides,seals,etc..I can pick up a set of Gt40P's brand new off a guy for about the same price as getting these heads redone.Is the Gt40p as good a head as the Gt40?Are there any issues to bolting these on as far as headers go and spark plug location?I am running a set of hooker headers now.Thanks for all imput.
