Is there a reason for that?forgive me but, do not ever use two gaskets. this is not the proper way to fix the issue. use some copper sealer from your local car parts dealer and the gasket you have. a little liquid copper gasket sealer and your gasket should do the trick. if it does`nt and you find there is no compression or weak compression. pull the head off and leave the jug. get a fine file and flat file the head and jug to match each other. do not!!! take to much off. this will cause the piston to possibly hit the spark plug on the up stroke. make sure you take just a little off at a time. too much and your piston will strike your plug. this should increase the compression and solve it. never run two gaskets. that`s not the way its done. that`s horrible advise!
30 years ago ,I painted a Harley oil tank and used my wife's oven to bake it . Worked great for the paint but OOOOOOOOOOO did I hear about the stink in the house .And be sure to get the approval of your wife/girlfriend/ line-in partner, before using the dining room table for motorbike work. That sounds like a sure way to get into trouble
The flat surface idea is the way to go. You can easily see if there are high or low spots that need attention. The head is easy...the top end of the cylinder is a little harder unless you remove it from the crankcase. A good flat surface is essential for proper head gasket sealing but I'd take Joe's advice before doing anything. If it runs good...in spite of what it looks like...leave it alone.

Maybe you should try washing the sink?Don't clean oily parts in the laundry sink either. 11 years later and it still has a black ring in it.
The glued down sandpaper is a safty thing for the good china on the holidaysAnd be sure to get the approval of your wife/girlfriend/ line-in partner, before using the dining room table for motorbike work. That sounds like a sure way to get into trouble

Kevlarr is dead on here, the file is a bad idea for working on an aluminum head even if you know how to run one your chances of getting it as good as using the glass and sandpaper is slim.Best way to dress the head (well other then on a mill) is to use a sheet of wet/dry sandpaper and a piece of double strength (1/8") glass as a flat surface.
It's too easy to screw up and make a gouge with a file, unless you can find a 4" wide file.
DO NOT USE A FILE. Unless you are a robot, you can never be certain you have taken exactly the right amount of metal from a mating surface uniformly. If this other guy has done this successfully, he is likely more lucky than he knows. More power to him. I only tell you this because I want you, and others who read this, to avoid learning something bad the hard way. Most of us don't have a lot of money, and this "file" suggestion leads down a path to a costly error.agreed, but i thought this guy might have some skill? sorry, just assumed someone could use a file properly. wez
