Need A Little help Please

Exactly what he says, increase it until it doesn't gain any further and set it back. But as stated with that much lift, though, intake to piston clearance can get pretty skimpy when advancing the camshaft.... A set of MP .028 head gaskets probably wouldn't hurt anything if you have it apart to check piston to valve clearance if the piston to valve allows it. If the compression is 11:1 or less, 100 octane would probably be worth some power over 110.
