Last thing, why the .050 thick head gasket? Use a thinner one (.039) to get a good quench area and a minor bump in the ratio. Is a 93 octane available by you?

The Edelbrock heads says they need the Edelbrock head gasket and it is .050. 93 octane is not available here, 91 is it.

With the smaller cam voodoo I get pretty good lift without a rough idle and keep pretty good street manners. At least that is the hope.
