Not sure why your tank on an 09 would be too close. I have a 107 build and I put MCR's in, easy to reach down and push each one in before starting. They are located next to the plugs in the heads.

Use S&S easy start cams no need to drill the heads or install compression releases, might be a cheaper route, only draw back is they sound a little funny when you shut down the engine sometimes
