Street and Performance vs TTI Motor Mounts and Headers

Has anyone used the Street and Performance (S & P) motor mounts and headers instead of TTI's for a 3GHemi A Body swap? With all the problems folks seem to be having with TTI's mounts and headers on A bodys, these seem like a viable alternative. S & P appears to make there own mounts, headers and other swap parts. You can see what swap parts they have by looking at their catalog pages 158-168:

In the middle of page 158 you can see an orange engine block with their A body mounts. The person I spoke with thought their headers would work with both power steering and manual. However, he suggested I talk to Mark to confirm, but he wasn't there. Anyway, anybody use S & P parts?
