[burnin oil]

Thermoquad. Perfect. Open chsmberd are fine. You need the flat tops and smaller heads to make the open chamber heads work. You want to keep quench on the tight side. Basically you will try and use port velocity to keep the fuel suspended and blown around the cylinder. Not to bad. Big ports will kill you on smog. When emmision testing I would do a tune up with hotter plugs. And captive discharge MSD box would help also. Basically anything to ensure a clean burn if you are worried about smog. I am lucky and live in an area where half the cars running around have the check engine light on.
