Camshafts and clearance

the air-gap is a dual plane intake.pull the cam out and see whats stamped on it if anything.
Is the air gap a good intake. Ok I will see whats on the cam.

I think before you get centered on anything you see what you have there. No sense in giving up power if you can run a bigger cam, or losing steam by mismatching. Pull a head and see what's in there. Also, I'd inspect the bearings. If they are bad, turn the crank too. If they aren't leave them alone. Changing just bearings could be asking for headaches.

Ya I will see what I have when I start pulling it apart. Ya I'am gonna look at the bearing, I though new bearing would be good instade of leaving the one on it. I'am gonna find out if its 30 over also.
