New High Back Seats On A '67?

I'm completely replacing every aspect of my interior soon and I would like to upgrade to some seats with headrests. Has anyone upgraded the seats in their 67 or 68? I'm wondering if a high back or headrests would hit the roof when moving the seat forward to get into the back seat. I'm making a seat delete so this would only be for luggage and dog to get into the back seat. I don't want to lose functionality, but I do want to be able to recline and to still move it forward.

I've been looking at the $300/pair budget racing seats on ebay, but I'm hesitant regarding their quality. I'd prefer not to have to drop $700 on the common options. Any ideas?

I prefer not to remove the seat risers, but I am over 6' so if I really have to, I could. I'm using a preformed carpet kit so I want it to fit perfectly and I'm not sure what removing the risers would do to that.
 
I also went with Procar Rally seats. I had them do a slightly custom stitching pattern. They weren't cheap, but they are *nice*. I am 6' tall and did not have to cut the floor pans, but if I was much taller, cutting would have been necessary.
