Re: copper gasket ..Calling all pro's
I agree with all said, but if your not after the best possible performance, then I'd just put it back together, Do a Compression test on it if you want.
But unless it's a high performance thing squish bands and such don't really mean much.
If you are after performance, do a squish test, without head gasket first.
I use a piece of 1mm solder, across the top of piston, head back on, turn her over, check solder ends with a vernier.
Unless you can get your final squish down to less than 1mm it won't do a thing.
If you have an angle fire head and you do get your squish to less than 1mm then you'll probably have more compression than you want.
