That Speedex head looks different from mine - though I do remember it ran pretty well.
I'd echo Ian's earlier comments, with any solid gasket you will likely spend a lot of time chasing water leaks. I'm not sure there's a real benefit vs a C&A type, personally I don't have any big issues with these so far.
I have run several engines with aluminium spacer plates under the block and these are not hard to make by hand (I'm using Reliant rods so they are 1/8" thick or thereabouts). Of course the number of oil leakage paths is increased accordingly but with silicone sealant it is manageable.
