Excaliber, do the center squirters have power valves? They didn't come with them, but you can put the front plate from a vacuum-secondary 600 Holley in them with it's power valve (used ones work fine...no moving parts). Jet the 660s down 6-8 sizes, and you've got a streetable carb. Without the power valves, they run waaay too rich at idle.
Also, .005 clearance is pretty standard if the pistons are forged. Cast pistons will run tighter clearance, but you don't want them in a performance motor.
Just some food for thought...oh, and I'll bet that baby screamed!
