as a side note of interest:
i have, in the past, very successfully re-used the multi layer metal gaskets via this method:
Separate the layers, and pick one. (if the head and barrel are lapped flat you only need one)
Re-crimp a sealing bead around all the ports *
Spray a good even coating of Extreme high temperature exhaust paint (the kind that bonds when it cures) on the "new" gasket (there are many brands, some better then others, and gloss black is always better for some reason. Hicote is ok, but ive had great results from halfords own brand)
when dry, assemble engine with newly refurbished gasket.
be sure to torque down to spec.
on first run : run engine with no throttle, let it warm up and cure the gasket paint for time as recommended on paint can.
turn off and let it cool to warm enough you can still touch it.
Re-torque the head
* you can only do this once without metal fatigue becoming a problem, but you are only using one layer at a time so you have spares for the future.
