Have you tried retarding the cam a couple of degrees? Another thing you can do is change the exaust rockers to a longer ratio. Of course you will have to check spring bind and valve/piston clearance to. I don't know my sb fords that well like these guys do but that 110 degree lobe center seems to be wild for a 10 to one motor. Chime in guys, but at that comp. ratio I'd bet that less overlap would unload the motor and it would run better and even be more civilized. A .6 lift solid lifter cam is the most I would run any small block motor on the street. To go any higher on solids will get you very increased cam wear to my way of thinking because the ramps would need to be too steep. In any rate the roller advice is sound, if you can afford the bucks. A roller will give your engine instant snap that you don't have now I'd bet. I'm a old Crain guy myself but I think the real smart guys would at least look at what Comp cams is doing. Make a phone call to those guys tech lines. That 2$ call will most likely save your motor I'd bet.
