Anyone have experience using these headers on a set of Indy 360-1's?
Looking for options to put on a stroked small block in a duster to replace a set of TTI's .
Al Yes sir, it's a full 1 tenth and 1.5mph gain over tti's. Did the exact test on a stocker pump gas 408, 10.80 deal, and also on a mid 9.50 deal. Cutt the flanges and they come out of car with everything installed. Way easy to work with. Both combos gained the same by switching. Just my track results, others may vary.

I have them on my 434", 360-1 headed small block. I too cut the flanges to make installing them easier. That's good to know, Did you see any improvement or was this a new build? Any chance you have some pics? I've been having a hard time finding much online. Al

i ordered a set at summit to swap out with my cheap 1 5/8" headers....should be here tomorrow afternoon. If you have some time i can post some photos during installation (will take at least 2 month, have to do other things before).
Michael
I'm sure i'll be into the install myself by then, but id still like to see the pics. Al

Guys be aware that some Milodon pans require a bit of surgery when used with the Hedman's.
Would you be able to fit a blanket on it after you clearanced the pan? My plan is to get a uncoated set and do any mods needed to fit a blanket on mine then have them coated. Al
