Thanks guys for the pics, tips, & links (my keyboard is acting up now from drooling at your rides).
The valve cover clearance was what I was worried about. Based on what I see, I think once I yank the SB, I'm just going to break out the cutting wheel and create a little clearance in the firewall....no reason not to. I've got a really good idea as to how much to hack out based on everybody's feedback. Murphy's law states that I'll probably be on the "lots of work side", so I might as well build in extra clearance in that area. It looks like nothing that a little fab work can't cure...and it if that doesn't work, I'll break out the 5lb hammer
