I have a relative stock 440 with a mild XE262 Comp Cam, 915 heads, all cylinders at 160 and one down to 125 and it still pulls 20 hg vacuum. 10-12 with a bouncy needle seems telling, as do the relative low compression readings. Hopefully the leakdown reveals something easy. Unfortunately mine did not!
Silver spring would get you the most gas early.. Maybe the .065 x .037 jet would do? Solve compression issue first.
