I went out to install my new M25 this morning and quickly realized that it is beyond my limited ability to mount the heads straight and level in the proper location on my 08 350z. Every surface is curved, angled, and very tight for access and i dont have any faith in my ability to get it right. However, i can relatively easily mount the heads vertically. Will mounting in this way reduce the effectiveness? If it will then i will just have to find an installer to do the work. What do you guys think?
Here is a picture of the mounting locations -
