Tunnel ram cam?!

I'm gonna run the 3.91s for now, but I'd like a set of 4.56s for days at the track.

I'm waiting to get the heads from the machine shop so I can cc them and see what I need to do. I'd like to get the scr close to 10:1, without touching the short block. If I can cut the heads and run thinner head gaskets and achieve 10:1 I'll be happy.
