I'm gonna be ordering a set of Edelbrock performer heads (60289's) for my 90 LX. I'm also buying my friends TFS street heat intake. I'm gonna leave the cam stock for now and get some 1.7 rr's to give it a bit more lift........ How involved is it to do a head/intake swap? I have never done this before. It all seems pretty straight forward, but is it relatively easy? Is it something that can be done in a day or two with basic hand tools? My friend who is selling my the intake said he will help me if needed. He has done a head/intake swap on his car more than once.
