70 dart swinger slant turbo build and mild restoration

That's what I was figuring as long as I didn't have it was down by the cold side of the turbo it would be fine . It was cold an rainy here today and I didn't get a whole lot done I do have a friend bringing his harbor frieght tube roller so I can roll the longer runners to clear the intake easier and not have it be a pain getting off and on the motor I looked at a video on YouTube of a guy who built a log style header and ordered short tight pre-beveled ends and it looked cool but there's alot of sharp angles for the exhaust to flow so I think longer runners with a 3 into 1 then the 2 into t3 flange will cut down on steep curves and allow the exhaust to flow since they are tiny to begin with.
Does anyone have any pics of the exhaust ports on the head with possibly a tape measure or ruler held up to help me reference and see what I'm working with on the head?

Also does anyone have that file I was looking for earlier I forgot what file format it needed to be but if you can get me a copy I'll send a set of half inch header flanges and T3 flange for FREE I'll even cover shipping this is out of mild steel not stainless. If not on here I was gonna start a new thread and see what I could come up with. Just looked and it's a dfx file
