SM Head Modifications on a budget

Well as a guy who's played with a die grinder a fair bit, but definitely not a head porter...

1. I'd use a set of templates and guidelines if it got me in the 280+ range with a set of edelbrocks. That's easily a 500+ HP head now.

2. If the video showed in detail how to address the short side and bowl areas, I'd go for it.

I'm not afraid of using a doe grinder and can do a good job with one, but I am afraid of screwing up a perfectly good set of heads in the process.
