With your low compression ratio and your tendency to not spin an engine up, I think that a Comp Cams 252H would be ideal for you. You don't need a dual pattern because you have headers, and you don't need the torque peak moved to a higher RPM.

The Comp Cams 252H will build higher cylinder pressure and is designed for your compression ratio. Also, these cams if using their lifters, an oil concoction with adequate ZDDP additive and properly broken in will last as long as the rest of the engine. It also will be easy on the other parts of the valvetrain.

Are you familiar with proper oil and break in for flat tappet cams? Most of todays oils are formulated for roller cams, not flat tappets, so you will need to use the correct oil and/or additive.

You will find much discussion in this forum if you are not already aware of the details of this issue.
