    The theory & anecdotal testimony is that on cold days/nites shutting down
    the engine hot w/open headers creates a natural convection draft thru any open
    valves.primarily ones on overlap thus subjecting the very hot exh valve to uneven
    thermal stress as colder air ends up pulling past. warped valve, crap compression
    burned valve after a few more runs. thats it

    so i guess that if i dont shove steel wool up my exhaust my engine is going to run like shit cause i will warp a valve and have shitty compression and burn a valve on the next run? wow. you learn something new every day. i knew steel wool had more than one use.

    As far as Durango/Dakota manifolds go, I ordered a set of Dorman replacement manifolds from Summit Racing and they do not fit. Passenger side manifold is too thick/wide and hits inner fender as well as the drivers side hanging up on the steering coupler. Also the dump on both sides is at a bad angle. They could be made to fit, but I felt it was more work than it's worth. I'm now in the process of modifying Summit brand Durango/Dakota headers to fit. A bit of work but it is gonna be a better fit and I won't have to use dual exhaust like the TTI setup.

      Easy install but Sold them long ago. Have a set of Doug’s on that car now. 90* oil filter adapter worked well. I have one of the early-a tti sets on my convertible valiant as well. Pita installing those but they look great.
