You can get a heat riser spacer from Corvette Central. And if you have access to any 1/4" thick steel, just make your own EGR block-off plate. And as far as plugging any vacuum ports on the carburator, plug everything except for the vacuum advance, transmission modulator valve, and power brake booster. There might be a EGR block-off plate in E-Bay somewhere.

Sounds Good
