Hey guys, noob here. Been lurking the forum for a few days now. Lots of great info. I have an opportunity to buy a 79 Mikado 4 spd 2wd longbed for $100. It has been sitting for about two years. The guy says it ran when he parked it but it needs a new exhast (SP) manifold or header. This truck will be used for economy. I don't care about power as long as it is reliable and economical. I have decided to de-smog it since I'd like to buy a header for it anyway. I also plan to do the other major upgrades such as carb, e-dist, e-fan, ect ect... I drive about 56 miles a day, 80% of which is flat and I usually only drive about 60-65 mph. If I can squeeze 30mpg out of it, it should save me well over $200 a month. More would be better though.

Anyway, which header would be best for my situation? Thanks,
Dan
