Has anyone here run stock edlebrok alumn. heads on a 428, then gone back and had them ported/polished?

was it worth it?

Noticable gains or losses?

Would you do it again?

what are some of the specifics? (cam, compression, etc.)

thanks for the info.

Trying to find a way to up the net horsepower a little.
would like to hit 500 to 550 at the flywheel on pump gas.
