    if i were to remove the head gasket and instead just rtv paste the top to stay on for higher compression is it likely that the piston will hit the spark plug? and will the compression be to high?

    i was thinking soda can head gasket, then i thought, soda cans arent meant to be made into head gaskets, so lets ask some people that maybe tried this before so i dont destroy anything on my engine.

    yeah you can do that. Put it on and turn the engine over slowly to see if the piston hits the plug.

    plane the head and jug perfectly flat before you do that. rtv will blow if there's any warp to the head.

    if i have to back the plug out can i just stick a washer in between it and use some rtv paste?

    use spark plug indexing washers, not regular washers, and don't use any rtv there.

    RTV sux. Messy and doesn't deal well with head temps and pressure. And the problem is the squish, not the spark plug. Learn about setting squish and use teflon tape for a gasket, it withstands higher temps.

    Just use a thin copper head gasket.
