Post proper quench

I know some of you are probably thinking, that would be and ice cold one about now....but...
I'm getting ready to assemble my engine and want to be sure and get it right. my take on it is this...quench distance is the distance from the flat portion of the piston to the deck of the block + the compressed gasket thickness. This distance should be around 0.040". This would mean that the only way to adjust the distance (without machineing the block) would be by swapping gaskets. What is a safe range to be in? Also, I am running forged crank...h-beam rods...domed pistons...and am wondering about proper clearance between the dome and head...spark plug area...thanks for all replies and I'll buy when I get this this running.....

Thanks
Nasty

You should try to stay with in .035 - .045 quench. Your correct on how to measure quench. For piston to valve clearance, you need to do a trial assembly. Place some modeling clay on top of the piston and roll the piston to TDC, remove the head and measure the thickness of the compressed clay.
