At 40% leakdown (and even 20% if you use high pressure like 100psi), you are going to hear the escaping air. If it comes through the case, you have bad rings or piston. If is through the exhaust, bad exhaust valve - if through the intake, bad intake valves. Was the engine hot or cold when you did the test. That engine has a problem you need to address before you do anything else. Additional hot rodding will not help the condition.

The engine needs to pass the California smog test.

DonE: I'll do some more checking today to see if I can figure where the leaks are. I would fix all this stuff before any mods.
Chet: The p/o had to lean things out to get it to pass. I looked at the DC site and saw he has a flow bench, so some head work is an option based on cost (like everything else). The SC cams (or some version) sounds like a good up grade.
