Fitting TTi headers on a 273

inertia said
I've been using a big flat file, (and sometimes a welder and/or grinder) to true and change the angle the headers leave the engine by filing the flanges since the 60's.
It.s no big deal, it's a last resort for gaining clearances, but used to be absolutely nec. to get the old headers to seal.

Thanks for your message.
This is my first Mopar so I’m learning all the time.
It looks like people have had this problem before.
It’s a good job I can come on here and ask questions.
I’ll have a go tomorrow- welding filing -milling etc.
Cheers
