i want a template as close as i can get to the 'extended port' design, any help is appreciated...



just want more hp and everyday driveability, i've searched and looked around and can't find templates for the 12a, but i may be doing a rebuild on a 13b sooner or later so if the templates were interchangeable... or something i dunno, let me know your thoughts, and where i can get templates for the 13b for my rebuild
