OK lets add this question. Aluminum rods need more piston to head. This has been discussed before. It varies with the type of rod,weight ,RPM,etc. Lets say the combo requires .060" piston to head. How much quench distance is there while the engine is running? If the piston touches the head at .057" do I have effective quench?

Absolutely, Why wouldnt it?

Heat soak with alu rods before you make a pass and the quench should be close to a steel rod engine, most alu rods need hot oil before you load them up anyway
