best plug angle on heads w/ headers

I have SLP 1 3/4" headers. I am looking at getting some cylinder heads and was wondering if anyone had recommendations on the best spark plug angle to work w/ these headers. I am thinking about AFR 190's they offer straight, angled, and L98 angle plug designs-

Dont know about the AFRs, but my Fast burn heads have angle-plugs and it makes plug access 10X better with the SLP 1 3/4 headers.

The TrickFlow 23-degree heads also have angled plugs, and some of them are easier to get to with my Hooker SuperComp shorty headers, others aren't any harder.
