I usually use "Gasket Remover" by permatex, + some 200 grit Sanding Pads (look like little black bircks) and some brake cleaner to wipe stuff off, then some 800 grit to finish the block surface...
Dont forget if your REPLACING the FRONT COVER there has been information relating to the front cover not being machined perfectly to mate with the block and makes the front of the head angle at a fraction of a mm in the 1st cylinder. Its ok with OEM and I think if you throw enough cpprgasket at the front cylit will be ok, but at high boost you can get head lift.
I havent had an issue with this yet on my personal car, running copper spray with Apexi hg but it is a real possiblity. Stay OEM unless you have agood tuner and are shooting for over 450whp.
OEM works just fine. wrong ecu or bad efi tuning and ghetto piggy backs kill motors , not oem hg material weaknesses.
