At least in theory, the roller lifters allow a steeper ramp at both ends, thus the valve can be opened quicker and held open longer (because it can be close quicker). So a roller cam is the solution to your problem. It would act like a bigger cam, without sacrificing manifold vacuum. Again you have so many cid to make power with, you may not need or want it.

Fully agree. Plus, of course, the roller cam allows you freedom to select the motor oil of your choice without worrying about low ZDDP and/or wiping out a lobe.

That was the thought I had, when I saw "I did a couple of full throttle pulls up to 4500 rpm in 2nd gear yesterday." I would think 'full throttle pulls' in 2nd gear would break the tires loose unless running wide, super-sticky rubber, perhaps even then.
