318 swap, couple snags

hey all, couple quick questions. swapping a 318 from an 86 diplomat into my 72 dart and i have hit a couple snags.

1. heat riser on drivers side hits power steering box. any way to remedy this?.

2. drivers side, small ridge on exhaust manifold hits a snap ring of sorts on the steering shaft. is this normal? How can i fix this?

this is going to be just a daily driver/runabout before anyone questions my engine choice. using a set of transdapt mount adapters. made them work with some shimming. dont have the tranny crossmember bolted up yet as i need to get a new mount. would like to try to finish this saturday morning so any help/advice would be greatly appreciated.
