Headman 1 5/8 headers pn#7850 and 4-speed fitment

They'll be fine.
Pain the get on. In regards to them hanging low...it helps if the car has some 15" +tires, front suspension stock height and in good shape because 2 of the drivers side tubes will hit deep swails, steep driveways etc.
One time I used a nail weld gun and sent puller to fix mine....another time I cut wheel the bottom face of the 2 tubes ...reshaped and welded a patch over each. Did all that because they're a pain in the *** to replace. LOL.
I found the tti's are about as much a pain in the *** to install in a 4 spd car.
90° oil filter has to come off, if you use of Lakewood bellhousing you have to either grind the bellhousing lipof or ding the header on the passenger side and then the driver side you have to move the over on the z bar and grind the back side off of it some... barely fits/moves between late mini starter, barely clears power steering box.by 3/8", center link still comes out, motor still lifted up, brackets removed for side to side movement.... but you don't smash them on dips and therefore don't have to change them.
Thanks for the input bud. Yea I have used both TTI and Doug's in the past, but for this project it's all about low budget fun.
