Sorry, just saw this....the issue I have is not necessarily a TTI issue, in fact their headers are a work of art...once installed...to me it's the larger issue of under chassis headers, a big block and an A body...even with a mini starter the headers must be removed to change the starter, to remove the headers the engine must be lifted enough to get the header out...gawd help you if the car still has factory k member, motor mounts and torsion bars. On my cousins car we installed the headers in coordination with the engine install so it wasn't horrible but the first time his car ate a starter we got a life lesson
