383+auto+headers

How well do the Tri Y headers fit on a 67-69 Barracuda with a 383 or 400.Is it possible to remove the starter without taking the header loose?Is it possible to remove the starter by only pulling the header loose?Do you have to remove the torsion bars to take put the headers in or out?I have a set of TTI's but was wondering if the Tri Y's were less of a pain.

Thanks,Jim
