I just bought a 65 coronet drag car. 511 cubic inch using a 400 block Indy -1 heads. Stock front end stock motor location as best I can tell. Hooker super comp headers. Have clearance issues passenger side with tie rod sleeve. Driver side torsion bar. Is there a better fitting header? I’ve used the same headers on other b body cars with a lot less issues. Any help appreciated Thanks

Wish I could help. I think quality control has gone way down. Bought a pair of TTI headers for my Cuda with 572-13 heads and they are the biggest pos I've ever had. Hit the starter (yes its one of the listed ones) and both banks land on the transmission. Absolutely no way to slide on the collectors. I guess I now know why TTI discontinued them.Its terrible that with what we pay dor something that is supposed to fit and they aren't even close.

I think my friends run hedmen headers for that yr. Pretty sure they use a RB though.

the best fitting headers.......are the ones you make or have made. It takes a lot of time to do a nice set, but afterwards you will be happy. IF you have the skills its not that much money, but to pay someone to make them its expensive.
An alternative is to take a set that some tubes fit and just make some alterations to the tubes that dont fit. Cut the collector off and change to a slip on style. Also cut the flange so one tube at a time bolts on. This alone makes installation a lot easier. Maybe you luck out and just takes a few simple mods to move one or two tubes around to make them fit well.

Have you tried adding additional header gaskets to move the headers away from the starter and to make them ft your car and motor better
If not, maybe you should: work: That has worked for me

Are these the 3 piece with slide on collector style? We have 2 sets and have had 2 other sets. Never an issue at the tie rod sleeve. The current low deck with SR heads fits w/o mods. The high deck needed a dimple of one tube on the pass side. Left the bolts loose, heated the tube, pressed it out against the torsion bar. Made a nice smooth dimple.

Cab I would need at least an inch to clear the transmission. I can weld somewhat but not enough to modify the headers. They will get fixed this winter. Already have it lined up. Passenger side will be pretty easy. Cut the tubes, spin the lower section and reweld. Drivers side the same fir 1 & 7 but 3 & 5 will be a major rework.
