Which headers / exhaust manifolds
Hey guys, so ive had tri y's on the car since i bought it a few years back and ive been using them ever since. The longer i have them the more i dont like them. My pitman arm smashes into one when i max out the steering, they heat soak my starter and they melt my clutch cable. I pulled out the whole exhaust system and im going to re do it.
I was thinking about going with shorties but ive been reading up on header selection and it seems like they can actually hinder rather than help especially with the stock (e7) head's exhaust ports.
So what im wondering is should i just go with some 289 hi po manifolds or is there another route that would be better?
the motor is a fairly stock 90 5.0 by the way, with a t5 behind it. i couldnt care less about the sound, im more worried about clearance and functionality

My personal choice would be the HiPo cast iron manifolds. I don't visit the 6,000+RPM range much, so those manifolds are bullet proof and trouble free. I would re-visit the choice, however, if I were to build an all-out race motor.

Based on your criteria..+ 1 for Al's comments.
Perhaps, it's a frame dimensional difference, but, I had no problems with TRYs on my junk in regards to steering and heat-soak issues. But, I did know there melting issues when running cable system. This is why I chose the conventional "Z" bar system.
Good Luck!

Before:
After:
Not headers but at least they'll flow better than stock and it was something else to mod!
