W/ the gt40p heads just use stock springs & rockers unless you plan on hittin it w/ a SC or juice... & they sell headers for foxbodys that are just for the gt40 & gt40p heads

always use new springs with a cam swap. Springs should be match to the cam. If you going to use a cobra intake you should port it to match the 70mm Tb you want to use. Cobras only have 65mm opening. Porting it is not hard it just takes a few dollars and a few hours. You should try and stay away from all the ford motor sports 303 cams. that topic has beed discussed over and over over and over over and over over and over over and over again. Bad choice in cam, pic another one
