Heads Question
Reply #1 –
Probably not at all.What year heads.The heads from the 70's and up were the same between the 302 and 351....just the 351's head bolt holes are bigger and you have to use spacers for the heads to install them on a 302.Find a pair of GT40 heads.They can be found at decent prices and will be great for your engine.The EARLY 351 W heads are desireable,but they were also made for leaded fuels,so,you'd have to have new valve seats installed.Too much work when the GT40's can do the same thing.What year is your engine (5.0)?If it's a stock 5.0,non-H.O.,then go grab a set of E-7 heads from an EFI 5.0 pickup.They are the same E-7 heads the Mustang has and will help a little.What other mods are done to your 302?
