Cam advice for more torque from 340

Here were my compression numbers back in August. I didn't do #5 or #7 due to the header.

Driver
1 141
2 135

Pass
1 140
2 140
3 135
4 132


Those numbers look pretty low to me.

I'd be looking into a new cam to get those CC numbers up since milling the heads is out of the question.

Crane 690141 & 690221 come to mind.
