sounds pretty good. I'd mockup & check actual deck height b 4 ordering the cometics to keep your quench. What octane? the angled plugs MAY pose a prob (someone will chime in). I am not a cam guy. I'd get a 3" mandrel ex system from the HP manifolds back like Andy did on his build (it's in the archives) & will need X pipe/proper muffs/rear resonators to keep the noise manageable. Yes .037" quench is perfect (measured in each hole) . Dont balance till you get the valve reliefs and or piston deck milled (if needed) EDIT you'll prob want the CR to b higher (forgot about the alum head effect)
