Simply put...
Its a copper head gasket. It doesn't need help to seal. If you need to use a sealant on your head gasket,perhaps you should lap the sealing surfaces to get a flat surface.
The blaster engine doesn't require sealant of any kind on that beautiful "Pure copper" head gasket.

i got mine sealed up tight now but a while ago i was having problems and i was about to but then i didint, but it has me wonderring why is it so bad?
What kind of problems were/are you having?
Explain please... Why do you think you were having a problem?
after installing my head (stock) it wasent sealing right, when i leak tested it, it was leaking all around the base of the gasket, i later found out i needed a new gasket and that solved everything
This tells me that you either had a poor sealing surface or were trying to reuse a secondhand gasket.
Improper annealing of a copper head gasket (which I may add I do not condone), caused by uneven heating/cooling, which can cause hard/soft spots, can make the gasket hard to seal.
The overall, soft condition of a new gasket allows it (when tensioned down) to compress into minor imperfections in the sealing surfaces therefore creating a perfect seal.
If one uses a sealant on a head gasket, this seal can be broken when after heat cycling the head is re-tensioned.
During heat cycling the gasket will be conditioned and require a re-tension, this may cause more compression of the copper.
If the gasket becomes marginally thinner during this compression, it will become marginally larger which may cause the sealant to move and break down.
I hope that I was not too long winded, but any solid copper gasket needs no sealant of any kind, it defeats its purpose.
