Advancing stock cam in a 360?

I know advancing 2 degrees from straight-up would be unnoticeable but the cam is currently at least 4 degrees retarded (8÷2) so I was thinking that little extra might help just a tad more and also compensate for possible future chain stretch. I'll go the full 4 degrees advanced as long as it won't increase the cylinder pressure too much. I'd love to just change the cam altogether but it's more work and expense (and risk) than I'm willing to deal with at this time. I'm not dead-set on anything just figured I'd ask y'all and see if anyone had experience advancing a stock non-HP cam.

@George Jets the ignition system is already overkill, Pertronix Digital HP CD box with their big coil (not canister-style). I put that stuff in back when I was still planning to swap in a built 440 but I gave up on that project soon after getting married lol.

It's not really hard to start it just takes a few more revolutions when cranking to light off compared to other Mopars I've rebuilt or tuned up. My Duster will fire off instantly on the first crank when it's warmed up.
