camshat selection can be very subjective. one mans posion is anothers cup of tea. the best suggestion i have to give is get on the phone and talk to some cam grinders. don't call just one, call several. with the lower compression you have i'd be a little careful so that you don't end up with a bunch of tuning problems asscociated with too much duration. i personally like engles because they've been so damn reliable for me. but, any grinder can find something thats a good fit for what you're doing.
