headers or manifolds for 4 door 318 valiant

having recently seen the header install problems for myself, well as long as you have time and patience you can get them done. cant say about performance as i am not knowledgeable enough. from an install point, it took an idiot like me 2 weekends to figure out to read the damn instructions first THEN try to install them. of course got everything buttoned up and the pow steering box had to come out - which meant undoing everything again. good news - i got both headers, pow steer box, mini starter and steering column installed in a little over 3 hours the second time. big difference with some experience and reading the darn manual. dont be intimidated by the install of the headers. i sort of felt like a rite of passage. and if i can do it anyone - literally - can.
