My name is Daniel, after reading your information on the GT40p headers and engine and the dimple reqiured for spark plug 3 socket. After looking at a photo of the header, will there be any issue with plug socket 4? I currently have a set of E7TE heads with the gt40 valves ported to the max, i dont have the bottom end power that i want, thats why i am considering the "P" head. If you know of anyone able to utilize these heads after I remove them, id be happy to get them to someone who can use them. Thank you for your time.
