I have a 91 f150 with a 302.. I just recently found out I had blown head gaskets so time to upgrade of course... I came across a set of gt40 heads as well as the gt 40 intake upper and lower. For a price I couldn't pass up... Got the heads figured out kinda a no brainer there bolt and go.... Now for the intake part is where the help is needed what all do I need to make it work kinda noticed I need a new throttle body and everything is on the opposite side and not to mention the egr valve is internal I guess? ..kinda lost any help would be great..almost thinking I'm getting into a lot of work I really don't have time for right now..

 

I did about the same thing 13 years ago. Like you said, fuel line is on the wrong side and you need to change many other small pieces. I ended up just using the gt40 heads and retining the truck upper and lower intake.

Another option is to find a junkyard with a mustand 5.0, an explorer with a 5.0, or lincoln lsc to steal parts from.
